The former leader of the kobold tribe at Gorrmoth’s Tower, overthrown by Gek the Necromancer after Gek discovered Gorrmoth’s spellbook and used magic to seize power. Mihilu was imprisoned under Gek’s rule.
The tribe’s original mission under Mihilu was to raise Kevin the White Dragon into adulthood — once they had a full-grown dragon as an ally, no one would challenge them.
After The Stumblers defeated Gek and freed the kobolds, Mihilu returned to the tower to thank the party. He presented them with a Dragon Whistle as a reward for liberating the tribe.
