Maxos is long dead but seems to still have an influence on anyone that enters his temple. I don't think we'd be seeing him in Divinity 3 but there may be references to him.
Maxos was the one who created the dragon knights thousands of years ago (when Dragon Commander is set) and when he was gone this passed on to the Patriarch. The Patriarch may create more of them for Divinity 3 if certain humans prove worthy enough. Info from Kickstarter updates.
