Well, I've found many such references between game series. But - I'd like to talk about a real life references ;P

Barnabus, The Necromancer
Commander Raze
Ddraigfyre (used as password for store)
Marian
Myrthos (sword)

:P
P.S. To further readers: forum allows users to change their name, so, don't blame me if they will do that >_>


The one reference I'd like to talk about: Ulthring set. Few ppl, who did read a story.pdf that comes with DD1 know that the Ulthring was a powerful arhcmage who served to Lord of Chaos. And, as explanation why there is no weapon for this sword: Ulthring had the mightiest sword in Divinity Universe - a Sword of Lies. Ofc, one can use it since the Sword will eat wielder's soul. Also, it was destroyed in DD1, AFAIR.
