Kig'ru is an older kobold, and has been Kenemon's servant since Kenemon was still a barely-hatched child.

He is a bit cranky, and takes more liberties with Kenemon's patience than is quite wise for a Kobold, out of an excess of familiarity.  But he is loyal, almost to a fault, and so has managed to stay just barely on this side of Kenemon's patience.
