char: Player characters. Information here is OOC until revealed IC.
loc: Locations. Different places have different levels of infection that fluctuate as the story goes on. Most of these places will be common knowledge, so it’s fine to refer to them during the RP.
meta: Important things you’ll want to refer to often, like your party’s stockpiles.
npc: Non-player character. These will pop up as they’re met in-game. Some have already been created.
ooc: Not usable as ingame knowledge, but there for a reason. Your character won’t know these things, but for whatever reason YOU should (e.g. how zombies work).
