Ruling from Castle Tréigthe, the old House Devliss was formally created by King Virion I when he gave the title of Baron of Treighte to Lugh Devliss. It lost its lands when Treighte was destroyed in a fire, regaining them under Queen Luciel when the Duchy of Balla and Treighte was created.
The last of Lugh's direct line was wiped out with no legitimate issue during the Imperial Wars, and with an eye to maintaining a foothold in The Kingdom of Tir they planted House de'Valice in Balla in its place. House de'Valice claims to be an offshoot of House Devliss but the evidence for this is sporadic at best and downright suspicious at worst.
