The final arbiter of the Underground stands rigid, magic crackling at their fingertips against an unstoppable tide of destruction. The end is a heartbeat away. you closes their eyes tight, steeling themself for the killing blow. It never lands. Instead, there is only a hollow, absolute quiet. When you opens their eyes, the battlefield is gone. An endless, blinding white void stretches in every direction, featureless and soundless. you has been swallowed by the Anti-Void.
