House Dhirbai was once a Great(?) House that ruled from Kotelga, a fortress world. After the wave, the world was largely crippled, but might have held on if not for ReCo forces who moved in on the world via Belhedan for Teraat. Kotelga held for as long as it could before it fell. Only a few members of House Dhirbai were able to escape to Teraat's Floating Palace as refugees, only to see Teraat glassed by ReCo just before the Autarch of Koyo Isu emerged(?)
