I wouldn't worry about it too much. This is a massive AU, so relying on canon information is next to useless aside from the overarching lore of the setting. That aside, you'll find just about everything you need to know about the basics of the AU in the first OOC. Basically, just treat this RP almost like you're reading Worm for the first time, a brand new tale. It's got different faces and names for nearly every aspect of the setting. We also do a ton of chatting on Discord about the exact specifics of things, both how they are the same and how they've changed.
