Amun-Her Khepeshef was a powerful pharaoh of The Serpentine people that nearly ascended to godhood in prehistoric times who would be banished to The BackHalls for most of recorded history, only reappearing in Quelmar when the halls were dispelled as part of the Fracturing of the Weave.
History
Banishment
Vestige: The Allip
After a long enough had passed in the halls, and Khepeshef's essence was slowly seeped away, taken and passed around like a cheap drug among the many banished of the halls...Khepeshef officially lost his mind. Becoming only an echo, a vestige, of his nearly unstoppable self, he became a shadowy form of tendrils and claws, sweeping through the halls still with considerable power, maddening and whispering to any creature that came his way.
As the Allip, Amun-Her Khepeshef hung on to only the faintest of drives which dictated his actions in the halls. One of those was the trusthworthiness of the Ten Captains who he fought alongside in his last minutes in Quelmar before the banishment. As a result, he would not attack, and would often overlook or even avoid, any group of ten humanoids traveling together in the halls. As a result of this small rule, it became more and more common to see groups travel in packs of 10 as they navigated the Backhalls.
