As part of a project I have been working on for a number of years I am doing my best to chart all of the noble families in BattleTech, As part of it I have the almost impossible task of seperating "Great House" from "Nation State" over on Sarna.
I know House Liao maintain a "House Crest" that is different from that of the Capellan Confederation.
I am pretty sure House Steiner replaced the "Lyre" of the Lyran Commonwealth with their house crest way back in the 2500s or so. (Going to check later)
Anybody know if the other three great houses maintain a seperate crest?
