Kaff Zarnak

 was a planet on the way to legion. It used to be a tropical paradise where Ray once took his wife on holiday. It later became a frozen world, because the moon of the neighbouring planet was knocked out of its orbit, causing the temperature on Kaff Zarnak to fall by 50 degrees in 4 weeks. The sandroaches were the only species to survive the big freeze. (AUDIO: Paradise Frost)
