Comyn Tower is attached to Comyn Castle in Thendara City it was also sometimes know as Ashara 's Tower. In ancient times the Tower was fully manned but during the most recent Terran occupation Comyn Tower has been inactive. Near the beginning of Domenic Alton-Hastur's rule as Regent the Keepers Council reopened the Tower with Lady Linnea Storn-Hastur as Keeper and Illona Rider as Under-Keeper. This happened in the book Alton Gift.
