Saxon who learned the language and manners of the British, as well as the art of medicine.

While King Gilloman of Ireland and Pascentius, son of Vortigern, fought at Saint David’s to defeat Uther Pendragon and conquer the kingdom, Eopa (one of Pascentius’s men) offered to go to Winchester, pose as a Christian doctor, and poison King Ambrosius Aurelius.

Pascentius promised Eopa fortune and fame if he were to accomplish this, and Eopa did succeed in assassinating Ambrosius. Pascentius, however, was killed at Saint David’s by Uther, and the Irish-Saxon alliance was smashed.
