Helena

Helena, known as Saint Helena in Roman Christianity, Saint Helen in British Christianity, and Helen of the Wells in Paganism, is a Roman noblewoman and religious figure across many religions.
It is believed that she was the mother of High King Constantin and grandmother of High King Constans, High King Aurelius Ambrosius Pendragon, and King Uther Pendragon.
In 497, the spirit of Helena aided Sir Alwyn of Oxenwood in defeating Gorboduc the Fiend for burning down her church in Medbourne.
