Blakciphrian is a combination between Ciphrian and Wistirian from The Astrian System. It can be fluid through them two genders but it doesn't have to be. They may also feel their gender has a viscarian, pistolian or luxian aura. It can be paired with another gender or be used on its own.
Sinstaian is the demigender version of blakciphrian, meaning it only has a partial connection to blakciphrian, with the other part being something else. The "other part" can be an unrelated gender to The Astrian System but it doesn't have to be.
