A Ulitharid is a subspecies of illithid, or mind flayer. they are roughly 9 feet tall with 6 tentacles instead of 4, 2 of which are about 8 feet long. they have a much longer maturing period in the elder brain pool then a normal illithid, 20 years instead of 10, so they are quite rare. they also have vaslty superior psionic abilities. In social status, they are usually leaders of some sort.
The Ulitharid Ahm Veckt was blood-thirsty mind flayer of vast proportions, he would tower over the shorter illithid with a superiority complex larger then he was tall.
