Unlike other rivers in the underworld, Cocytus' entire area is shown to be frozen, and the ice is thick enough for one to walk over in most of its extension. Its immense area makes Cocytus one of the major areas in the underworld, and the river stands in the deepest area of hell, where the division with the Hyperdimension that guards Elysium is located, as well as the temples where the judges and Hades usually reside (that is, Caina, Antenora, Ptolomea and Judecca). The largest area in Cocytus is the Eighth Prison, a plain of ice where those who stand against the gods (such as all the saints who fought in the Holy Wars) are sent after death. The ice is permeable after one's body is dropped and left over it for enough time.
