An ancient Shetou council house dating back before Shetou was a thing. Vloz'Khress was originally a house in the underdark long before drow started adapting to the surface, and they maintain a strong sense of tradition for their old ways. Of the many houses, Vloz'Khress is one of the most hardcore and reviled by Alnae and independent colonies. Also known as the house of demons, Vloz'Khress maintains the ancient tradition of summoning and enslaving demons to do their will to the point that they have achieved a phenomenal level of expertise in demonology. In the space age they were reluctant to go anywhere other than Thenica, eventually as times changed and they needed more resources to situate their power they established their first colony. That first colony would later be abandoned for a new colony on SV1's molten surface where they have made good business with mining operations.

Once one of the great pillars of drow society, Vloz'Khress is a shadow of its former self. Its tendency to house seriously crazy people (dealing with demons your whole life does that to you) has not helped it as politics of the verbal nature became more and more prominent in the modern world. Another factor has been the increase in power of other houses. While it languished about the pits of the underdark other more adventrous houses found wealth and power on the surface and then across the system's planets while Vloz'Khress remained stagnant. The rise of Shetou was also a major blow to its standing as this incorporated the existing eastern civilization of the world above it, a union that demanded to split power even further by necessity of the empire growing bigger. Vloz'Khress didn't get any weaker in terms of economics or influence, but more seats on the council had to be made which by simple math reduced their power.

On the upside, members of House Vloz don't like to wander around much and tend to stay in the underdark of Zonaricht-Thenica where its old seat of power remains and their major colony on SV1. Vloz'Khress is not popular with outsiders as the leaders could easily be in The Raven as demons drive them mad day after day and they insist on keeping angry demons around. That being said, Vloz'Khress priestesses are among the most powerful pandem summoners in the system.

They notably hate House Song for its position of power among drow politics despite having never in history been ruled by a drow or lived in the underdark. During the merger of the drow nation and the eastern one to create Shetou, Clan Song was a monstrous influence in the new empire and one of the only eastern houses that stood up to the drow ones fearlessly enough to even earn Quaintana's approval. As such, Vloz has held a rivalry with the dragon house for a very long time. This rivalry is returned fiercely, and Song Yi was the one that destroyed their first colonies and has bombarded their SZ1 mining facility more then once. The world awaits the day the Matriarchs clash in a battle of ultimate pandem and necrocarnum. There is even an entire comic series in circulation asking the hypothetical question of how that war is going to go.

They have a prominent specialty in demon summoning and multi-summoning. Every prominent member of the house can bring at least a pack of demons to their aid at any time. The powerful Vals can summon fully intelligent demon strikeforces at will.
