Marcille Donato is an elven mage and member of Laios' party. She hopes to find a way to create a safe dungeon. Marcille is intelligent, principled, and loyal to her friends. Despite this, she can also be very high-strung and has a difficult time dealing with things far outside her comfort zone (such as eating monsters). She has a lot of confidence in her ability to cast magic due to her background, and can feel lonely when she is unable to help the party with her specialty.
