This sword was blessed by the tears of Raziel, the angel. Terribly destructive, it's powerful enough to enable its bearer to attack the most fearsome enemies.
Raziel seems to be a reference to the character, Raziel from the Legacy of Kain/Soul Reaver video game series.
Raziel is also an angel in Kabbalah, Jewish Mysticism, said to be the "Keeper of Secrets" and the "Angel of Mysteries."
