I've played both DD and DKS and having done so there are a number of canonical inconsistencies between the 2, some can be explained by the passage of time within the world [such as the people of aleroth and thus rivelon mistakenly assuming goemoe's healing well 'was' the source and not simply drawing from it as well as the growth of the city since the time of the divine] however some are a bit...stickier...i haven't played beyond divinity so i don't know if it helps answer any of these...but the 'big' one is that dragon knights arnt mentioned 'once' in DD, and dragons are given 'very' passing notice when your working to reconstruct the dragon armor...you fight a few 'dragon riders' though i suspect the dragons these beasts are riding are no more sapient then the brainwashed husks damian uses to fill out his airforce in DKS
the lack of elves is answered in the game as well mentioning there exile or destruction by the black ring. i just thought id bring this up....if anyone has answers for the many inconsistencies please fill me in, if not...well ive said my peace...laters.
