Me and some friends who love the game are working on a D:OS 2 wiki @ Orcz:Divinity Original Sin 2 Wiki
It's going to be very detailed and have all NPCs, locations, as well as strategy guide etc.
Still a work in progres but check out some sample pages: (SPOILERS obviously)Fara
(NPC page)Every Mother's Nightmare
(Quest page)Fort Joy
Also feel free to add stuff and help!
