Kireseth is important in the mythology of Darkover; the Blessed Cassilda, ancestor of the Comyn, is depicted in paintings as holding a bouquet of flowering kireseth. In The Forbidden Tower, Damon Ridenow and his circle fit together the mythological pieces and prove to themselves that a female Keeper need not be a virgin, or even chaste, to act as the center of a telepathic circle, if she uses kireseth. They are seen as rebels, and have to fight a telepathic battle to keep their circle and the "forbidden" tower they have created in the overworld. Their use of kireseth is viewed as blasphemy by many (ironically, since this use is portrayed in religious art) and when Damon's daughter, Cleindori (Dorilys Aillard) attempts to use this knowledge as the Keeper of Arilinn, a legitimate tower, she and her followers are hunted and killed. Cleindori means "Golden Bell" and is a nickname connoting her blonde hair with the appearance of the kireseth flower.
