Kurtulmak

The Lost Servant
The god of the kobolds is Kurtulmak and he wanders a maze on Avernus after being tricked by the gnomish god Garl Glittergold. Since then kobolds have hunted gnomes to appease their dark god, and hoard treasure for draconic masters.

Kobolds serve dragon masters because they see in them the true rulers of the world. It reflects a deep insecurity in themselves, they are weak, small, and cowardly. Kurtulmak taught them how to steal, how to make traps, build tunnels and use their numbers to overwhelm their enemies.

Kurtulmak in a way despises his kobold children, he sees their weakness reflected from his own. Tiamat has never cared for Kurtulmak, and he knows it. Should his kobold followers ever find a way to release him from his eternal torment, perhaps he can appease his master by bringing her the skull of Garl Glittergold to add to her treasure hoard.
