Temple of Ra: Journey to the Underworld is a Dungeon Crawler/Roguelike/Puzzle/Adventure hybrid game. Players take control of a recently deceased Egyptian Pharaoh, Ptolemaios II, who has to seek redemption and ascension to the afterlife, for being a greedy and cruel ruler in life. However, the evil known as Apep has risen in power at the time, and has turned the Egyptian underworld to a deadlier and twisted labyrinth.
When Osiris attempted to stop Apep, he was able to break off one of Apep's fangs. Forged into a weapon, it is used like a boomerang due to its curved shape, although users tend to become corrupted after prolonged usage.
