Yastar

Yastar is a Mage in Ultima IX, living on an island near Valoria.

When the Avatar found him, he was surprised to have a visitor, but quickly came to business. Yastar had been experimenting with Bone Armour and offered the Avatar an instruction manual of how to make the helm of the Bone Armour. The Avatar agreed, and managed by following Yastar's instructions to create the bone helm.
