|— Cerberus to Orpheus in in Rogues|
|Current Alliance||The Place of Eternal Darkness and Rogues|
Cerberus guards the entrance to The Eternal Darkness. He was once used by Achlys to kill her enemies, but he was freed from her spell by Orpheus. The two are now good friends, and the Cerberus will run to Orpheus' side whenever he whistles. The Cerberus can speak English an is very intelligent, but prefers to stay quiet most of the time.
- The Cerberus was named after a monster in Greek Mythology. In Greek Myths, the Cerberus was the "pet dog" of Hades and guarded the underworld.
- Just like how Orpheus played music to tame the Cerberus on this wiki, the same thing happened in Greek Mythology.
- Most of the time, all three of the Cerberus' heads have different expressions on their faces. Each head also speaks with a different voice.
