Zwei is a very controlling and stressfull deity. They often command Zvette and Zxene to do things for them, and formulate all the plans within the three without much input from the others. They can be very bossy but the others don't mind, unless they are being unbearable. Zwei likes to think of themself as the leader of the Z deities, even though that's not the case.
Parvati: Written in the Stars
Zwei appears in the first episode of the fiction, alongside their fellow deities Zvette and Zxene.
