Sa'Vasku
The Sa'Vasku are extremely long-lived semi-aquatic lifeforms resembling giant nearly-immobile jellyfish. They are an ancient race that has seen many space-fairing species rise and fall. Little is known of their race except for the fact that they seem obsessed with balance and are fearful of change. They believe young space-fairing races like humans are too naive to be left unchecked and they ruthlessly oppose their expansion into space. Sa'Vasku technology is biosynthetic and their spaceships are alive, genetically created and grown for specific purposes. Their construct ships are equipped with various "weapon organs" that generate energy beams or launch spore projectiles.
