I find myself idly thinking of Elias Glaspi and I gotta ask: Genderfluid?
In fact, there is a motif of duality in the Shang-La world, especially among those considered “different” from ordinary mortals. Tsourai, immortal creatures, can choose the sex and gender that feel right to them, though they eventually settle into it. Phollie, the mystical entity behind the tsourai, is non-binary—or perhaps even entirely gender-indifferent.
Melalo, who exist closer to the world of the tsourai, have two “faces”: one is scenic, and the other is their usual self. They inherit a stage appearance and a pseudonym from their teacher. Elias’s teacher is Ragneda, known on stage as Marestail. So his scenic appearance mirrors Ragneda’s, but he performs as Marestail II. If Elias were to take an apprentice, they would inherit it as well, becoming Marestail III.
But there’s a small detail—Latorians don’t have surnames, only given names or nicknames. So when a melalo gives themself a surname, like Elias Glaspi, it likely means he is preparing to found a new melalo dynasty under that name.
