Aeduan wears his Carawen monk cloak at all times. He is described as having brown hair, blue eyes, and pale skin. Iseult notes that while he has the features of a Nomatsi, his eyes are not folded as deeply and his hair is not as dark, concluding that he is not a full tribesman.
Aeduan appears cold and uncaring. However, his rugged exterior and blood-lust can be misunderstood. Aeduan comes off as a stone-cold killer but holds compassion for many people. He has saved Iseult countless times, spared Evrane, and rescued a child from the unnerving, cruel raiders.
Very little is known about Aeduan's past, although a recurring memory suggests that his mother had died in an incident involving fire.
With nowhere else to go, he joined the Carawen Monastery, and by the time he was thirteen, he'd sworn the Carawen vow to protect the Cahr Awen. Due to his Bloodwitchery, he was later trained to be a mercenary, and was mentored by Monk Evrane. Sometime after his induction as a Carawen Monk, Aeduan reunited with his father, the "Raider King."
Aeduan is introduced as a mercenary monk working for Yotiluzzi, a gold Guildmaster in Dalmotti.
Sensory Type - As a Bloodwitch, Aeduan can track the blood scent of others and sense their magic.
Physical Capacity - Aeduan is capable of controlling his blood (can push it to the extreme limits of his physical capabilities for certain lengths of time).
Regeneration - He can regenerate lost limbs and heal injuries.
