Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General In-jokes and references to other Divinity games?

I've found several references from previous games:
-Arhu. He's been around since DD in a form of a white cat. Apparently later this became his permanent form (should have heeded those warnings about dangers of polymorphing).
-Zandalor. He's a mainstay character in the series and you can meet him late in the game in the Source Temple.
-Bellegar. The quirky rhyming wizard from Divinity 2. He also sprouts several references to Dragon Commander game and powerful wizard Maxos.
-Zombie Jake. There's no end to him in Divinity games apparently.
-Zixzax and the pyramids. They've been around since DD.
-Duke of Ferol. Yet another dastardly ruler from that unlucky DD duchy.
-Thelryon. What the above poster said - he's been around doing evil stuff since DD.
-Healing stones dilemma. Was first introduced in DD, but there you could save both patients if you're clever. When I first seen this in D:OS I thought I gotta find me some magic mirror.
-Talking wishing well was in DD as well.
-Two talking skeletons at the mill in Cyseal. Been around since DD, although they were funnier there.
-Several books that relate to the upcoming events of DD, like "Coming of the Divine", "Dissapearance of Seven Gods" etc.
