So I have names for the parents of Silent now
Father: Stone Feather (Apomattax)
A large tan and crimson griffon, chosen as chief of Silent's home village. Heavyweight
Mother: Robin Wing (Cassius)
Broad winged Pegasus with frilled feathers, giving her silent flight. But her broad wings restrict flight speed.
Black and yellow mane, crimson eyes, and a ghostly grey coat. Former thief.
