Gabriel

A herald of the Lord. Went missing after an engagement during the war, when he refused Michael's command to return to Heaven?, so that he could protect a human he loved.

Stories say that just before a child is born, Gabriel whispers a secret in her ear, then swears her to silence. The child carries the secret, unknowing, in her soul all the days of her life.

Sandalphon believes this story, and has discovered a way to extract the secrets from human souls.
