What this mod really needs isn't literally a wiki, but there should definitely be a page here in the discussions (or something like that) detailing all of the different modifiers, events/anomalies (with spoiler warnings), and especially relics. I've tried looking around online and unless it's staring me right in the face there isn't anything like that. Almost every relic added by this mod has a casus beli paired with it, but I'm not going to risk my empire going to war over something I don't know anything about and when this mod adds so many relics it's impossible to memorize them all until you've done twenty or thirty games with it.
TLDR; I'd really appreciate a discussion detailing the exacts of what this mod adds because it ends up very confusing without a basic run through. If anyone has a good list of the relics specifically I'd love if you could share it with me.
