"Seonon, sad Seonon, has a history as dark as the waters of the Llyn Tywal. Here Algana the Fair stood atop the tower lamenting the death of her beloved Gorawan, until the spirits of the Otherworld were themselves overcome with sadness and allowed his shade to ascend through the pool for a day and a night to console her. In latter days this land has often been ravaged by Sturgian raiders, and not far from here lies the wood where King Aeril disappeared, clearing the way for the rise of Caladog."

Tasiel, a character from the Digital Companion of Bannerlord, is said to live in Seonon in a tower tending to her families' skulls which a collection like that is not actually bizarre or strange and in fact is common, although Tasiel is not actually present in game so cannot be found.
