Ok, as part of my Nash X Inaya fan fic, I introduced royal guards. Some are partially based to how in the movies, Typho is the nephew of Panaka
Carnus Astor: First guard to Inaya., then captain of the guard
Allos Astor: brother of Carnus and the first guard assigned to Nash when she got engaged with Inaya, then Hazun’s Port Marshal
Ceratos Astor: Allos son from the first marriage (first wife died in the Nihil Crisis), and the second guard Nash got
And not a guard, but pretends to be one, Torvo Astor: a human-Alcedian hybrid one year younger than Princess Enira, daughter of Nash and Inaya. Torvo is the son of Allos from his second marriage, an Alcedian named Ptaria.
Torvo and Enira are friends since they were very young. While Torvo doesn’t live in the castle, he always likes to pretend he is Enira’s guard, which in practice is being an accomplice to her shenanigans, or him teaching her what he is taught about self defense
