During this event the Halcandrians' first home, the planet of Keystal, was evacuated do to the newly created Void Termina absolutely destroying the place.

Timeline

 * Void Termina is created and summoned by Ticker into Keystal, leading to destruction of the planet. Several of the planet's native wildlife, including the Purple Velvet Butterflies, go extinct in the earliest parts of the war.
 * The Ancients at first declare war on Void Termina, and unleash thousands upon thousands of troops on Void Termina, several of which were the very hardy Crystal and Seraph Crystal Dragons. Many of these dragons die, leading to the extinction of the Seraph Crystal Dragons and near extinction of the Crystal Dragons.
 * The current leader, the queen Fantasize, attempts to surrender, and is immediately killed. Fantasize's dead body forms the Realm of Thought, and because she couldn't accept her fate, she becomes a ghost wandering the Realm of Thought.
 * Ticker is told by Fantasize that Tinker has created Void Termina, and he confronts Tinker about this. Tinker banishes Ticker from his realm. Ticker tred to return so he can save the Ancients, but a forcefield by Tinker keeps him from getting in, even by portal.
 * The Ancients beg Tinker to save them, so he gives them a few Warp Stars so they can escape. However, there wasn't enough Warp Stars, so only a few escape. The Warp Stars were also very heavy, so most of the Crystal Dragons had to stay in Keystal.
 * Asphyxiate, Tonight, Lockdown and Twilight discover the four missing pieces of the Immortalkiller, and together use them to banish Void Termina.
 * The Ancients try to resettle down, but the land is now so barren of life that it's inhabitable. They are forced to continue with the evacuation, and when they do evacuate on the Warp Stars, the Warp Stars take them to the pocket dimension that is now Halcandria.
