Between Beyond Divinity and Divinity 2. This is clear because Lucian was alive at the end of Beyond Divinity, and is dead in this game and Divinity 2.
Then again, in OS2, Lucian is stated to have died in 1233 AD. 1233 is when Damian was banished to Nemesis. Lucian wasn't "killed" by the dragon knight until at least 1238.
Basically nothing here makes any damn sense.
