Sypha Belmont

Sypha Belmont, née Belnades, was the wife of Trevor Belmont and mother of Simon Belmont.

Events of Mirror of Fate
She was killed in 1073 by the Werewolf forces of Dracula, leaving Simon to be raised by mountain people.

Her soul was kept in a frozen shard below Dracula's Castle where it is discovered by her son Simon in 1101. Despite Simon never realizing who she really is, she joins his quest to protect him with the power of her love. This power is known as the Spirit of Belnades.

Later during a battle with the Necromancer, she is captured only to be released after the battle.

She also helps to convince the spirit of Michael Gelhart Schneider to join Simon's cause, giving him the power of the Spirit of Schneider.

Spirit of Belnades
The Spirit of Belnades is one of Simon's two Spiritual Powers available to him in the game (the other is the Spirit of Schneider). It can be used to absorb damage received by enemies or stage hazards. As a type of Magic Power, damage absorbed reduces Simon's magic meter.

Trivia

 * Though belonging to the Belnades clan, it is unknown whether she had magical powers during her life.
 * The Spirit of Belnades actually represents two distinct characters, both Sypha, and a woman who was a healer in ancient past, centuries before Simon's quest, whom pilgrims used to travel to visit her shrine.
