Peerie Canto

 was a planet.

It had a Desert of rocks sharp enough to slice through the soles of shoes, and air that it hurt to breath in. The sky was the colour of vomit and there was a continous thunderstorm.

The Wraiths were trapped in a Quantum Anvil on the planet.

Ace had a recurring nightmare where she was transported to this planet and attacked by Halogi-Kari.
