Orleason

From MTG Salvation Wiki

Orleason was a Thran city-state. When the Thran Alliance revealed the atrocities Yawgmoth had committed during his exile and told the Thran they would declare war if Yawgmoth wasn’t stripped of his privileges, Orleason voted that Yawgmoth could stay. Not much later the city was laid under siege by the Alliance. The artificers in the city switched sides and Orleason fell.
