Seal

One of the set of 7 seals that imprison the elder really bad god.

Each is in the form of a disk with a yin/yang symbol across the surface, and holds very strong magics.

When broken it will trigger a planar rift between the current location and the plane in which the elder really bad god is trapped...

The size of the rift/hole is dependant on the total number of intact seals. The fewer intact seals, the larger the rift!
