I did a little research because I had never heard of this angel. Orifiel is an archangel, one of the angels that are part of Jewish, Christian, and Muslim traditions. Unlike the more charismatic angels like Gabriel, Rafael, or Michael, Orifiel is a bit more mysterious. In fact, I could only find information about him/her on a couple of angelology sites. On these sites, Orifiel is described as the angel of the wilderness who helps save the wild areas of earth.
We like the image of frogs as angels of the wildnerness!
