As quickly as it started, everything stopped, the world around you ravaged and warped by the massive displacement of energy. Stone and concrete buildings, once tall, were now twisted into horrible shapes, the souls used in the construction of the realm pressing out of the walls in atrophied, vaguely-humanoid shapes. Fog began to roll in as an icy wind blasted you from somewhere deep in the realm.
Behind you, where the building once stood, gaped an enormous pit. A massive, ragged tear in the very fabric of warp-space.
You could feel dread's cold talons working their way into your mind as you gazed into the wall of fog, your limbs heavy with fatigue. Your companions looked similarly, their bodies hunched and shivering.
Rodwen's whispered voice cracked the silence. "It knows we're here..."
You shook your head, swallowing hard, determined to keep strong. It didn't go past you that the swarm was gone, either destroyed or having fled from the crushing blow to the structure of this reality.
