Evelis Lona Mathanith
The current (and hopefully permanent this time) Mathanith heir, who came to the wedding.
Long face, firm mouth, large gray eyes. 
Stuff here from the Mathanith head's bio, about how Evelis came to be heir and the scandals. Also I think Velederien mentions that the scandal continued while they were offworld--look that up in Court of Dragons.
Tolden was her primary hanger-on back before he went offworld; his parents wanted him to marry her.
"Had we all been marked by the war, I am certain we, too, would have been rewarded by our sovereign. the good fortune here, Irlain, is that we were not so marked. I doubt any of us would have been able to earn a land grant the way Lord Lauvet did." 
"Our elders have their allegiances, Lord Lauvet. But those allegiances are not set in stone."
