This is Uriel, angel of light. He is the angel who guarded the gate of Eden with a flaming sword ("You punk humans get off my Paradise lawn!") and is often represented with some fire in the palm of his hand. Perhaps not surprisingly, he's associated with the sun. He's also the patron of poetry, and he <3s art in general.
When he is not around art-y things, he's sort of a grumpybear, but he's still an angel. He will listen to your problems and offer a wing to cry on. His answers just might be...blunter than expected. He's currently a librarian, and he just arrived in New York.
(Those of you who watched Lost might recognize his PB as WAAAAAAAAAAALT's Dad XD)
