Okay, copying this from Discussion

Basic Notes

There will be no catching Pokemon during this arc, for in-universe reasons explained later on. If you want a Delta on your team, you'll have to:

* Get it cleared with everyone else. I had to with Igneous, so everyone else who would want one needs to go through the same process no matter who they are.
* Have a good in-universe reason for why the Delta wants to follow you around away from Holon. This is the much easier part of the process.

Additionally, all Pokemon you wish to participate in the arc with must be in your team at the beginning. Same in-verse reasons as above.

Geography

We're using this map:

As for details...

Location

Holon is located north of Kanto, with Joulant Town connected to Cerulean Cape. That happens to be the only reliable way of reaching the region, since there are no ports.

Delta Islands

This set of 17 small islands, each of which could have its own name, for those who want to contribute, protrudes from west of Joulant Town. Each one is prominently inhabited by Deltas of a specific type, but you're free to have the secondary type of any mon be whatever you want. The islands are arranged like this:

Unnamed Island

The island to the far west of the map has several different species, but the most notable is the massive amount of Delta!Golett and Golurk. Essentially, it's Umbra's Bionicle Shout Out island.

Distant Island Chain

These are incredibly far away, beyond the horizon. On an island in the exact center of the island chain, there's a strange circle of crystals around a crater. Near-identical crystals have been found on the main landmass.

Mirage Forest

This massive forest covers almost half of the region, even completely surrounding Holon City. Rumors are, a Mew appears here, but nobody knows for sure. Except for the J-Team, who will no doubt meet it at some point.

Holon Ruins

These ruins may seem trivially small from a bird's-eye view, but in fact extend deep into the Mirage Forest, and even underground. They used to be a city for a large civilization... one which existed around 600 years ago, in fact.

Somewhere deep within the ruins, there is a path which, to Palkia's dismay, leads to one of the distant islands to the northeast.

Oh, and there might be magical artifacts. Such as armbands. Or any other items you can think of. You just have to search for them.

Mt. Ohmeg

This mountain has been dug through for years, in a search for those strange crystals. The search was called off when the crater from the Distant Island Chain was found, but the tunnels still exist. The tunnels link Cergus Town, the area near Lake Volata, the Mirage Forest, and the Calor Desert.

At the northernmost end, a spring runs water into Lake Volata, which flows through the Mirage Forest and down into Lake Holon, cutting Holon City in half.

Calor Desert

Not much is to be found here, but the trek through the desert is the only way to reach the unnamed island with the Delta!Golurk. Hope you brought plenty of water.

Warrior Clans

In the area between Lake Holon and the bulk of the Mirage Forest, four Clans of feline mons live. Being territorial, no doubt they give visitors hell just for attempting to get to Holon City. The four clans are:

WindClan

• Led by a pure Flying-type Delta!Persian

• Inhabit the open fields in the center

• Mostly Flying- and Normal-types

RiverClan

• Led by a pure Water-type Delta!Delcatty

• Inhabit the edge of Lake Holon

• Mostly Water- and Ice-types

ShadowClan

• Led by a non-Delta!Liepard

• Inhabit the area around the main path to Holon City

• Mostly Dark- and Ghost-types. Poison-types are also fairly common.

ThunderClan

• Led by a non-Delta!Luxray

• Inhabit the  edge of the Mirage Forest

• Very diverse type-wise, but a large number are Electric-types.

Clan mons, like most Deltas, tend to have stats that differ from normal mons.

WindClan

• Generally high Speed stats

• Weaker Defense and/or Special Defense stats

RiverClan

• Higher Special stats

• Lower Physical stats

ShadowClan

• High offensive stats

• Frail defenses and HP

ThunderClan

• High Physical stats and HP

• Low Special stats and Speed

Mythology-wise, they believe the Mirage Forest Mew was the original member of StarClan, which consists of cats who had ascended to a Higher Plane of Existence. Additionally, they hold the Legendary Beasts in high regard, although Suicune is significantly less respected than Raikou and Entei.

The full list of accepted mons:

• Meowth line

• Sneasel line

• Skitty line

• Zangoose

• Absol

• Shinx line

• Glameow line

• Purrloin line

Eeveelutions are not allowed, unfortunately; they're foxes, which, in the books, are not to be trusted. Sorry, Espeon lovers.

Clan Battles

Given the nature of a "clan", battles with them will mostly be in groups. Seeing as the arc coincides with Conquest, it would be a nice link between the two if the Clans had kept the battle style alive. Due to this, Clan mons will also have Conquest abilities rather than main-series abilities. While that's something we still need to figure out on that half of the arc, no doubt we'll have figured it out by the time the clans appear.

I'll personally be practicing writing Clan battles before they are needed in the first place, taking elements from both Conquest and the Warrior Cats books.

Magnetic Storms

Magnetic storms are near-constant in Holon. They screw with electronics, and all Pokeballs will malfunction fairly early on. All Pokemon will be forced out of their Pokeballs. This is why catching Pokemon during the course of the arc won't be possible.

Deltification

Turning a Pokemon into a Delta can happen one of three ways:

Hatching/Evolution
These are the points when the Pokemon's body rapidly changes; they are also quite vulnerable to external stimuli such as Delta radiation during these times.

Extended Exposure
We'll be leaving Holon before this can happen, but it can easily be implemented into backstory. Be warned, this is the most likely to cause ill effects.

Delta Crystals
With enough crystals and enough energy - energy which may well have to be provided by Mirage!Mew - one can instantly Deltify a Pokemon, or revert a Delta from such.

Delta!Legendaries

Delta legendaries are obviously an iffy subject, but there are a few which could be fairly reasonable.

Delta!Mew
Essentially, the Mew rumored to appear in Mirage Forest is a Mew with Multitype, minus the need for Plates. Instead, it Transforms into a Mew of any type it wishes. This is the only definite one.

Delta!Deoxys
It exists in the TCG. Perhaps whatever meteorite it came on might be the original source of the crystals Scientists had been studying?

Delta!Latii, Delta!Shaymin, and any other "plural" Legendaries you can think of
They'd be exclusive to the Distant Island Chain if they do appear at all.

Plot

To start, we need a reason to go in the first place. One possibility (and feel free to contribute your own):

One of the PCs finds out one of their ancestors was important in Holon, and go to the Holon Ruins to find out more
This provides a nice link to the concurrent Conquest arc. I may well have Ancestor!Alyssa be a Conquest!Holon native for this purpose if nobody else has ideas.

Then, GASP! Stuff happens, and we're stuck in Holon until we find a solution! Possibilities:

One or more J-Team mons have been Deltified, and are ''not'' happy about it.
It gives us a reason to explore the entire region, in an attempt to find a "cure".
Mon/Trainer Separation
Perhaps we got lost in the Mirage Forest. Perhaps someone kidnapped somemon. Perhaps, perhaps, perhaps. Point is, it's a nice way to implement that subarc plan. Only issue is, if it's the "getting lost" option, we're likely to stay in one place until we find each other again.

After Schroedinger's Number Of Trials, we finally solve our problems, and decide we've had enough of the place. And so, with new knowledge of the past, we return to Kanjoh, where we plan our next actions.

A small question. Would Delta typing transfer through breeding?

I was wondering how viable having a Normal-type Wooper in a small group of Dragon-type Wooper would be.

Tagg: Fixed it. And perhaps one or more of your mons can get involved.

Zeal: It would transfer, yes, but it's restricted to the types of the parents; for example, a regular Houndoom breeding with a Dark/Water Houndoom would result in any combination of Dark, Fire, and Water-types. You wouldn't end up with a hypothetical Grass-type Houndour out of nowhere. So if, between those Woopers' parents, at least one was part Dragon-type and at least one was part Normal-type, then yes, it would be viable.

Reposted from the Discussion Forum on TvTropes:

So, I have a plan for what my characters will be doing during Holonquest.
I) I will be introducing Kerri-Lynn's Anti-Counterpart Sophie.
II) Related to I, I will be explaining why she's in Holon.
Sophie is another graduate of Mauville University, a Pokemon Professor that specializes in Pokemon relations in the wild. She was drawn to Holon because of a rumor of a group of Delta mons that have developed the equivalent of a city-state in a remote part of Holon, which she has dubbed Ravnica. (Yes, this is going to be a huge MTG reference. Deal with me a bit.)
This city state is broken into ten groups of Delta Mons, which she through talks with Psychic mons, she has mapped roughly.
1) The Azorius Senate:
Azorius is a very orderly territory, kept in one of the many temples in the area of Ravnica. It is guarded by a Psychic/Flying Luxray named Isperia. Azorius maintains order in the city-state of Ravnica.
2) The Orzhov Church:
Orzhov is a very ornate territory, almost garishly so. It's never quite daylight or night there. The Church of Deals is maintained here, where an afterlife in the Orzhova Ghost Council can possibly be achieved... for the right price.
3) The House Dimir:
What? What is this Dimir you speak of? Shh... It's not supposed to get out... No one really knows where the territory marked by the Dimir is... Because every member of it is a Psychic/Dark Delta that steals the thoughts of anyone that gets information on the Dimir. It is currently leaded by a Psychic/Dark Zoroark named Lazav.
4) The Izzet League:
"BOOM! THAT WAS AWESOME! LETS DO IT AGAIN!" Is something you can usually hear emanating from the Izzet League. Nominally, they are the scientists that make sure the infrastructure of Ravnica (Roads, technology, etc.) is continually improving. But... Really, they just care more about making Weirds (Delta Rotom of conflicting types like Fire/Ice, Fire/Water, Rock/Electric, etc.)The Izzet League is lead by the Psychic/Dragon Druddigon Niv-Mizzet, and to a lesser extent a group of his 40 top followers, the collection of the Firemind.
5) The Cult of Rakdos
"A Party that you'll Die for~" One huge Fête Worse than Death. Lead by the (thankfully, usually slumbering) Fire/Ghost Gengar, Rakdos. It's the... entertainment district. Murder, cannibalism, and other atrocities are commonplace here, and only increase when Rakdos wakens.
6) The Golgari Swarm
They are the agriculturists of Ravnica, and completely in tune with the cycle of life, death, and undeath. Every mon is either Bug, Grass, Ghost, or some combination of the three, and is almost definitely in some sort of decay. It is lead by a Grass/Ghost Cacturne named Jarad.
7)The Gruul Clans
"CRUSH THEM!" A direct quote from Borborygymos, the Giant Fighting/Ground Conkeldurr. The Gruul clans aren't actually lead by Borborygymos, but he leads the biggest and strongest clan, and thus has the respect of almost everyone in the clans. They hang on the outskirts of the city, and occasionally storm in and crush stuff to reclaim for the clans.
8) The Boros Legion
The military force and lawkeepers of Ravnica, they are lead by the Angels, a group of Fire/Flying Winged Gardevoir, that lead the charge into their very numerous battles. The most powerful, Aurelia, usurped control from the previous leader, Razia after she was disgraced. A select group, called the Sunhome initiative works with the Izzet League to develop new warriors, armors, and weapons.
9) The Selesnya Conclave
The nature keepers, the Selesnya embrace all into their loving group. They think themselves a tight-knit family, but most of the rest of Ravnica believes them a Nature loving brainwashing cult. They all hear each other's thoughts through Mat'Selesyna, the voice of nature, which is interpreted through a trio of Grass/Psychic Sudowoodo bound at the root to the ground, in total called Trostani.
10) The Simic Combine
The Simic Combine is full of strange mutant mons that seem like hybrids of other mons. It is lead by the Grass/Water Milotic Zegana, though she claims that she's no more in control than anyone else in the Simic Combine. Few outside of the Combine go into it willing, mostly because they're terrified of the (often huge) beasts that wander around.
III) Psyche and whoever wants to tag along will be investigating a competition between the guilds over the control of Ravnica.
IV) ???
V) Profit!
Thoughts?

So the Holon arc starts in a few weeks, yet I feel as if the Holon Region as a whole doesn't feel fleshed out very much at this point, which makes it a bit hard to actually plan anything to do.

Can we work on fleshing things out a bit? Like discussing how a lack of Pokéballs effects Holon culture? What each of the five towns is like? Or even what sort of Pokémon live where, if possible?

I'd say Holon City, it's right next to the Holon Ruins and Mirage Forest.

Yeah, Holon City works best for the museum.

Looks good, Straw, though I thought we decided Holon isn't actually connected to Kanto but is Shrodinger's distance north of it?

Something I made to help plan some sort of connecting paths between the locations. Subject to changes.
