Kursaal

 was the name the Gray Corporation gave to their Class Two leisure world in the Cronus system. It contained a huge theme park and other amenities.

History
A thousand years before the Gray Corporation arrived on Kursaal, the planet had had non-human inhabitants - a vulpine species. Humanoids infected by the Jax virus arrived on Kursaal and built a cathedral on the planet. The humanoids were killed off by the wolf-like creatures native to the planet, who then became carriers of the Jax virus, turning into werewolf-like humanoids. They went into hibernation until more humanoids landed on the planet. Kursaal became their homeworld and they were worshipped by the other species in the Cronus system, who they eventually transformed into Jax. Their archaeological remains concerned the pressure group Helping All Life Forms (HALF), who wanted to halt construction of Kursaal lest it eradicate invaluable artefacts.

Several thousand years afterwards, the planet was found by humans. Although the Gray Corporation saw no great distinction between the theme park and the planet, others certainly did. There were some who remembered that the planet's real name was "Saturnia Regna". Prior to Gray's purchase of the planet, it had had a sparse population of human or humanoid colonists, most of whom had been subsistence farmers, and all of whom had been bought out by Gray Corp.

The Eighth Doctor once took Sam Jones to Kursaal to give her a luxurious holiday. He enticed her to go by having her "imagine Disneyland meets Babylon 5". However, the TARDIS landed a few years too early and they became involved in the controversy surrounding the construction of the resort. (PROSE: Kursaal)
