Tasiel

Lives in Seonon, Informant of Istiana

Tasiel is a character in Bannerlord's Companion Edition. She's an informant for Rhagaea in Battania. She lives in Seonon tending to her families' collection of skulls. The Red, a companion from Battania, is another skull collector. She despises Caladog and is presumably a daughter/sister/cousin of Ergeon or the daughter of Aeril that was married off to Caladog.

She could either be part of fen Derngil or fen Uthelhain and could be the daughter of Aeril that was married off to Caladog. In the lords.XML a character named Aireen once existed, this could be the name of Tasiel before the Digital Companion was created.

Using her portrait shown in the companion DLC, we can create a look-a-like. The head wear she dons in the drawn portrait is not like any item currently in game so I chose this desert headdress instead. I also used Ergeon, the brother of the late high king Aeril as a template or starting point and then used the drawn portrait from the Digital Companion as a reference when remodeling and shaping her face.
