It'd be very interesting to know what happened to the paladin: did he/she end up getting corrupted by the Damned One or did he bring the news to the Divine One?
Also, he opened a rift to another place: we can see that. However, I suspect the place was likely Nemesis since I doubt he'd know the coords of any other dimension unless they were already written within the Book of Coords. And I suspect he'd quickly try and find a way back to Rivellon: it's not like Damien is going to waste time trying to find him. He's got better things to do.
Also, why the hell did my character trust the DK so much? For me, I was pretty ambivalent: I enjoyed the DK's humor but since he was from an opposing side, wouldn't some caution have been far better? Besides, he didn't really do anything to merit much trust from my character except for fighting in the battles which he was forced to take part in, unless he wanted to die.
