When the Hero sought to enter Hades for the Rite of Courage, he bribed the guardian with food. He offered a gyro, a pepperoni pizza, and a box of sokolatak-ya. Cerberus then allowed him passage through the Gate of Hades.
Cerberus, the character in Quest for Glory V: Dragon Fire is based on the mythical Cerberus of Greek legend -- a three-headed dog who guards the gates of Hades. In the game, the player can bribe Cerberus (as described above) or alternatively, the Wizard may Calm or Dazzle him.
