in terms of "endgame"? there's high level fights, there's space crafting, there's the Occult Crescent as an open "field operation", kinda like an open world "Raid"
my FC broke up quite a while ago due to drama and I haven't joined another (I have my own one person FC thing for an additional house and access to airships/submersibles, but the other person who helped me with it has since left the server)
