Mantear was the ruling House of Andor before Morgase won the Third Succession War in NE 972. At this time, the Daughter-Heir, Tigraine, was missing. This was due to the advice and Foretellings of Gitara Moroso, the advisor to Queen Mordrellen. House Mantear had begun to run heavily into male children and, as such, there was no one for Mantear to put forward from their own House as a suitable candidate for the Lion Throne.
