You are a pokémon living in an MD-like world (no humans, mystery dungeons everywhere, exploration guilds/societies/teams are a thing).

>Setting
You and every other players are in [insert town name here] for X reason, a new settlement located at base of a mountain range and near a narrow river. The climate is cold and it keeps getting colder as winter approaches at a speed noone had anticipated. Needless to say, you're going to be stuck here for the entire season. The best thing to do is getting ready for what is going to be a veeeery long winter.

>About the settlement
-It doesn't have a name yet, first to name it gets to choose its name
-Its establishment isn't funded and/or supported by any organisation : it is entirely independant
-There are plenty of mystery dungeons around the town

>About mystery dungeons
-Basically the same as in the games with a few exceptions
1-No wands
2-No orbs except for escape orbs
3-No pure seeds/reviver seeds
4-The pokémon in the dungeons aren't actual pokémon, they only take their appearance and have the same moves. They are spawned by the dungeons themselves and disappear on defeat. They are generally weaker than actual pokémon.
5-This doesn't mean there can't be actual pokémon lurking in the dungeons

>Character rules
-No legendaries
-No mary sues
-No edgelords
-Everything else is up to you

>Goals
-Survive the winter
-Explore some dungeons
-Build a lore
-Have fun
