Ciel

Ciel is a human planeswalker from the plane of Revio. He was born impoverished within a small tribe in the Aer region, however, his charisma and natural ability to bring people together eventually lead to the formation of Cieldana, the new name of his village under his control. He joined forces with other nearby groups to form the Red Dynastic Kings, and ever since he has ruled his kingdom.

Magic
Ciel focuses less on magic than other planeswalkers, and prefers to fight more melee based combat. However, he does have magic that allows him to enhance the strength and durability of both him and his allies. This can also allow him to take an ally who is on the brink of death and give them enough energy to finish the fight before dying, allowing them to die a warrior's death.

Trivia

 * Ciel was the first card from Riddles of Revio to make it into MSEM via the set New Horizons, which took in one card from every set submitted to MSEM.
 * Ciel's role in the story of Riddles of Revio is minimal, due to his inclusion being largely determined by having a design and art that worked, rather than filling a story role.
