Despite the uncertainty of Omnath's actual existence, a real site on a high mesa of Ondu was dubbed the "Prison of Omnath". The site was safeguarded by a binding circle of strange globular swamp-growths, stone hedrons, and animal bones. The circle created an eerie sensation in those who approached it, deterring them from approaching the circle's center, where a huge pit leads deep into the ground. Those who got too close died to the destructive surges of power that lashed out from the circle.
Religious pilgrims from across Zendikar traveled to the Prison of Omnath on a twice-yearly basis to perform the "Ritual of Lights", a ceremony designed to protect the world from the release of Omnath. During the events leading up to the Rise of the Eldrazi, however, the ritual was disrupted and Omnath was set loose.
