The kobold flinches only slightly when the fire disappears, and then considers. Kiri does seem friendly, and more interestingly, they do seem to think that the kobold is a person. (Probably; as near as the kobold can tell with so little to go on, anyway.) There are worse things she could spend her time on than making friends; if they are a mage, maybe they'd be willing to swap spells, and if not, well, knowing a friendly fire-or-illusionist spellbearer still can't hurt, if there are troubles again.

The first thing to do, then, is clarify that she is a mage; surprising Kiri with that wouldn't be very polite. First, vocabulary - "Kiri do of fire; Kiri is of spellbearer. Kiri is of mage? Mage do of spellbearer."
