Prince of Albion and Henrietta's cousin. He and Henrietta had a romantic relationship, but is faced with their status as cousins. His vow to the water spirits is to one day be able to show his feeling to Henrietta without needing to hide it from the public.

Wales is a triangle wind mage, and in the second season, he showed that nobles of royal heritage can combine their magical power with other royals and create power above pentagram grade (possibly up to decagram grade with two pentagram mages).
