Kurtulmak, kobold god of war and mining

The god of kobolds was a vassal of Tiamat. When the gnome god Garl Glittergold, gnome god of trickery and wiles stole a treasure from Tiamat, dragon goddess of evil hoard, she sent Kurtulmak to retrieve it. Garl lured his pursuer into a maze-like cavern, then collapsed the exits behind him, trapping Kurtulmak for all eternity.
Kurtulmak is a hateful deity, one who despises all life except for kobolds. He especially hates Garl Glittergold, gnomes, and fey creatures that enjoy playing pranks. He taught the first kobolds how to mine, tunnel, hide, and ambush. He is dominated by his emotions — intelligent, but not wise. Arrogant and prone to gloating, he carries grudges, has a huge chip on his shoulder, and spends a lot of time fashioning elaborate revenge scenarios against those who have disrespected him.
