Nobody knows what the Syetvenans are supposed to be under their cloth coverings. Any attempts to figure that out have resulted in assault charges. The only uncovered parts of Syetvenans are their mouths and the area surrounding them, and their air-filled floatation organs. Access to the Syetvenan homeworld is restricted to only other Syetvenans. If you try to fly there yourself, you’ll be stopped by their top-notch security team. Syetvenans are the only known species in the galaxy that can perform minor magical feats without Rezver conduits. They won’t tell you exactly how they’re able to do magic naturally, but they’ll be happy to sell you spellbooks and staffs that let you perform single spells.
