Cryoians are a cold class creature that are found on the Planet Crynos. their home are located in subterranean of massive icecaps and are generally made of ice or rock
the Cryoians joined the Galactic Counsel because the ships that they use can absorb beamer type weapons and they are much better for diplomacy.
the weapons that the Cryoians developed are meant to freeze opponents and are able to freeze up a Attacker's hull in which makes the hull brittle and are usually finished off by a Ice Torpedo
the last remaining Cryoians are in a Aetherian space Citadel where the Aetherians have converted into a hospitable area for the Cryoians to remain until the Aetherians either Terraform one of their worlds or find them a new one that exactly matches crynos world
