As a child, Uriel, along with Amriel, Raphael, Micheal, and Gabriel, were all taught by Lucifer. Eventually, Uriel contracted a disease that was spreading throughout the Angels in Heaven. It resembled a tar-like discoloration on the skin, and those who possessed this trait were quarantined for the protection of all others. Wanting to help, Amriel broke in, even with the risk of herself being infected. This brought the attention of Satanel, who used fire to burn the infection from Uriel.
