Underworld ยท Greece
Cerberus
The many-headed hound guarding the gates of the Greek underworld.
Legend File
Cerberus prevents the dead from leaving and the living from entering casually. He is not evil so much as absolute: a boundary with teeth. Heracles capturing him becomes one of the great heroic labors because it requires entering death's domain and returning with proof that even the underworld can be confronted.
Source Framing
Greek underworld myth around Cerberus/Kerberos as Hades' watchdog, including Heracles' underworld labor and variant head counts in ancient sources.
