This angel is not specific to any religion but a symbolic fantasy being. Life can be hard and sometimes filled with sorrow. Here she offers a prayer in rememberance of those who have died before their time.
Sargon the Half Blood. One of the rare Immortal Children, half human half elf with the immortality of their elven parent, Sargon turned his back on the elves and gave half elves a bad name. This led to them being called half bloods and being treated as if they, too, would turn to evil. Another Immortal Child is said to be the only one to be able to kill him.
