The Hogwarts Express

Post Season 8, the ex-paladins stumble upon Camp Half-Blood, and it turns out that they are all clear-sighted mortals, except for the fact that Keith and Lance aren't fully human. (I can't just tear away their parentage like that.) Lance was given the blessing of Poseidon, giving him the ability to control water and talk to all horses and sea animals. Keith was given fire control by Hephaestus. Hunk was given healing abilities by Apollo. Pidge was given the ability to control plants by Demeter. They were all blessed with knowledge of the wizarding world. They were sent to become teachers of Wandless fighting at Hogwarts during Harry's 8th year.
Ages:
Keith - 23
Lance, Hunk - 21
Pidge - 18
