One of the things you can do in the Drow city is go and fight duals. You fight two fighter duels then some mage duels.

Well, the last thing the last fighter did before dying was to summon a whole pile of monsters, including an Ogre.

I sent Imoen in for the next duel. First thing that happens is that the Ogre, still there from the last duel, comes up and pummels the %#$@ out of Imoen, killing her!

$^@%%&* duelling area. Why can't they clean up after each match?
