Mytos looks at the girl first with unmarked suspicion, then with his usual frosty irritation. "His kin are trying to bring out the power of some god of theirs, the 'Dragon Below,' whatever that is. There's a human priest who seems to be both insane and helping them. I think we need to exterminate them; I may not know many things about Gods, but I know plenty about fools trying to draw power forth from a nigh-godlike source. These kobolds could get significantly more dangerous."
As he says this, he walks non-chalantly to the kobold, taking out the bloody cloth he'd wiped his sword with. Placing the blade against the kobold's throat, he turns back to the group. "So it's decided that we leave him and continue? I would keep him alive so far as he could lead us to the cave, but that's assuming he's trustworthy enough not to run us into a trap. Can we track the fresh escapes quickly enough?" He seems unnervingly ready to slit the kobolds throat once he finds that the group is done with him.
[spoiler]For reference, I've decided that when leaning towards his saner side, Gerand is Gerand. When he's angry/violent/etc, I'll call him Mytos. It just sounds more evil.[/spoiler]
