Activities
Mostok was a faithful supporter of Khan Ubar khel Muhif and followed him to Umara when Ubar became Caliph of that city after the revolution. As Ubar's second-in-command he was referred to as "ur-Khan Mostok." Mostok believed that life in Umara was making Ubar soft and he never referred to him as Caliph. He distrusted the natives of Umara and believed they would one day turn on the members of the Astok who lived within the city.
