William Costello

Prince William Costello, the warrior son of King Daniel Costello of Aelia, is well-known among royal circles, though not widely beyond them. Despite being in an environment where secrets are as valuable as fortunes, he manages to keep his personal life private. During his childhood, he emerged victorious in the sole tournament held in Diairesi, defeating all challengers, with his most significant win being over the much younger Prince Kylial. This match is thought to have sparked the ongoing rivalry between the frequently conflicting western powers of Aelia and Vacous.
