Merlin

Merlin is a mage and former member of the Seven Deadly Sins who carries the mark of Gluttony. Known throughout Britannia for her magical mastery, she serves as a mentor to Vivian and previously taught King Arthur of Camelot. While she temporarily stepped away from the Sins to assist the king, Merlin intends to return to the group to help fight Hendrickson once her current duties are complete.
