Daemon prince of Kal.
Kal-injau was advised by the efreet Ikari.
Kal’s sigil was the dragon. The daemon prince was described as half-man, half-dragon and as large as a score of men.
Based on the reports of the slaves rescued from Kal-ereska, you believe it possible that Kal-injau survived the eruption of Dragonmaw and was nursed back to health by the kobolds, who now worship him as “half-god, half-brother”.
