The nightmare world dissipated along with the dark Annan.
But Annan, whose body was radiating a bright glow, was not immediately cast out of the nightmare world:
[The world has been purified]
[You have completed a powerful purification, and your evaluation has been greatly improved]
[You have found the real world line, and your evaluation has been increased]
[You have reached a reconciliation with another self, and your evaluation has been increased]
[Comprehensive evaluation——A]
[You have received the instance clearance reward: Banished Memories (Annan Winter)]
[You have received the World Purification Reward: Blood of the Time-Reverser]
[You have gained 200% Spiritual Essence, Perception +1]
[Based on the nightmare's location, you have obtained the Holy Light Imprint of the Charioteer]
[Based on your Book of Truth, the Holy Light Imprint of the Charioteer has been transformed into the Sacred Light Imprint of the Charioteer]
