Leon Lucario, alongside his son, Wesley, is working as an independent Dungeoneer outside of the Custodian Guild’s official authority. Otherwise, not much is known about him. Leon and Wesley appear to live about half an hour away from Glimmering Port to the northwest.
While working, Leon wears a belt on which he can hang a longsword and a small pouch for holding items.
Leon claims to have a contact within the Custodian Guild who feeds him information via use of a Connection Bead. When a request must be urgently assigned, Leon is available as a resource to ensure it’s taken care of. He’s stated a preference that these jobs aren’t credited to the Custodian Guild, but has also demonstrated a willingness to be flexible on that front on account of “not wanting Gardevoir on his ass.”
As of recently, Leon has taken on the main party in the same role and established an indirect line of communication to his contact within the Custodian Guild so they can functionally operate as an underground Independent Team.
