The following characters are NPC/side chracters that are meant to be either replacement league members (i.e Terrance and Ramiro) for the Elite Four in other regions or gym leaders meant to fufill the other minor gym leaders spots in the Galar league. They don't carry too much of a role in the main fanfic besides making a appearance in the side chapters and further worldbuilding. Below links lead to other characters in the Immortal Epeeverse.
