Although initially scattered across Coldharbour, the invasion forces quickly reassembled. After destroying the Great Shackle and breaking through the last line of Dremora defenses, the armies of Tamriel were able to access the Endless Stair. After a heavy fighting, a small group of the best entered the Planar Vortex with Meridia in order to use an artifact called the Light of Meridia, while the army distracted Molag Bal. This artifact destroyed the vortex entirely, resetting all progress Bal had made on the Planemeld.
However, Molag Bal had simply retired to his palace at Heart's Grief and planned to attempt a second Planemeld when he had recovered his strength. In order to stop this, the Five Companions journeyed to Heart's Grief and confronted Molag Bal using the Amulet of Kings. Mantling the power of Akatosh, the Soulless One faced the God in single combat and banished him to the Void, freeing the souls he had captured and ensuring an end to the Planemeld.
All leading generals received Vestige hero ancillary and all armies victoriously returned to Tamriel!
