I wanted to say that i don't agree with the elves, i wanted to say they are wrong... but i cant, it is clear that the people of the dungeon need to suffer a bit to understand what they are doing, i am not proud of this idea but well you harvest what you sow and they aren't a little bit careful with what they are sowing.
That dwarf and his cronies deserved that... and the elve fighting style was really interesting, creative use of teleportation magic.
