Round 1—Surprise Round
Carrach advances on the first of the two creatures, drawing his dagger as he moves. Attacking, he sinks his longsword into the grey body [roll of 10 on d20, +4 melee with longsword, total 14, hit; roll of 7 on 1d8, +2 damage, total 9 damage]. The creature is staggered and in very bad condition.
The back creature fires a bolt at Carrach and hits, the bolt penetrating deep into the outside of Carrach's right thigh [5 damage]. The wounded creature takes a small step back and fires at Carrach also. His poor luck continues, however, as the bolt flies wide and high, clear over the heads of the party.
From the back of the party, Qoll mutters a few brief incantations and all of you can feel the blessing (if you can call it one) of Wee Jas [bless, +1 on attack rolls and saves for 2 minutes (20 rounds)]. He then moves ten feet backwards, away from the melee.
Sando ducks toward the shadows and starts to pad towards the melee.
Vorik lobs a small, sickly-green orb down the hall at the attackers, but it bounces away harmlessly.

Carrach -5 hp, 13 remaining
Round 2
Carrach advances five feet and slashes at the creature with his longsword, finishing it off easily [roll of 20 on d20, +4 melee with longsword, -4 TWF, +1 bless, total 21, hit; roll of 7 on d20, +4 melee with longsword, -4 TWF, +1 bless, total 8, critical denied; roll of 3 on d8, +2 damage, total 5, creature killed].
Tekk advances towards the front of the combat, close enough to heal folks if needed.
The other creature lets out a loud whistle and fires again at Carrach, but misses wildly. He backs up another thirty feet and attempts to blend into the stone, but fails miserably.
Cassandra pulls out a vicious looking chain and closes on the remaining creature, swinging her chain in a wicked arc [roll of 11 on d20, +4 melee with mw spiked chain, +1 bless, -1 power attack, total 14, hit; roll of 7 on 2d4, +3 damage, +2 power attack (2H), total 9 damage]. The creature is clearly staggered.
Sando continues to advance.
Finally on his toes, Rothgar rushes in at the creature and rips open its chest with his longsword [roll of 17 on d20, +4 melee with longsword, +1 bless, total 22, hit; roll of 4 on 1d8, +2 damage, total 6 damage, creature killed]. His opponent crumbles to the floor, into a pool of its own murky ichor.

Aftermath
Attached to one of the creature's crossbows, you see a small ring holding an odd, rectangular rod. Sando recognizes the rod as bearing gnome craftsmanship and is pretty sure it must be a key of sorts. The end of the rod is shaped vaguely like the gnome glyph for "N." Additionally, Qoll is nowhere to be seen...
