Clavis is the Guardian of Darkness within the Angelique universe, wielding authority over the elemental force of darkness. He maintains this essential role consistently across multiple series entries, including the original Angelique game, Angelique Special 2, Angelique Trois, and Angelique Etoile.

His background identifies him as one of nine elemental guardians supporting the Queen's rule by balancing cosmic energies. This collective duty involves maintaining planetary stability through their command of Sacrea, the spiritual powers governing the universe. Clavis's specific connection to darkness fundamentally positions him as the counterpart to Julious, the Guardian of Light, forming a classic elemental duality that shapes their interactions and responsibilities.

Physical descriptions consistently characterize him with raven hair and ivory skin, aligning with traditional associations of his elemental domain.
