SPOILERS!!! AVOID READING THE TOPIC

Hi everyone, bought the game in EA, but cannot access it and play right now. I've been a a fan of Larian and Divinity series since I played BD (yeah, strange start). I am very interested in lore and plot of the games. Can anyone spoil the plot of DOS2 here? Will Lucian appear in the game? Will Damian? How is source connected to the divine power?
