It was the end of the Underworld.
The crack in Tartarus continued to spread and finally divided Elysium into two. The massive rift ran across the entire earth, cutting the artificial land like an invisible sharp blade. After Elysium fell apart, the crack further ran across the dry Styx and spread to the wilderness at the edge of the Underworld.
Hot magma spurted out from underground. In some smaller fissures, steam columns were as high as hundreds of meters high. The rock layer began to collapse into the endless void while an energy storm rose from underground. The once solid earth of the Underworld became wavy like melted cheese before it wholly sank.
Kronos led the ancient Titans to escape the fast-disappearing world. They clung to the tower of the Underworld, which was also rapidly collapsing, and climbed up to Mount Olympus.
