Florana

Florana was thought to be one of the most beautiful planets in the galaxy, as well as one of the most peaceful. The Third Doctor once told Sarah Jane that he always came back from Florana feeling "a hundred years younger." (TV: Death to the Daleks)

History
The Fifth Doctor took Tegan and Nyssa to Florana early in its history, when it was a barren planet. He found that a Dalek had crashed and taken control of the planet, pretending to be its god. It was destroyed by Thane, who attempted to take over himself. This resulted in the killing of many of the inhabitants, and the flowers Florana was named after grew from their ashes. (AUDIO: The Elite)

By the 30th century, Florana was discovered by the Earth Empire and used as a dumping ground for toxic waste by 36 species. (PROSE: Original Sin)

On 5 June 5968, there was a peace conference on Florana between humanity and the Chelonian Empire. The Third Doctor and Sarah Jane Smith arrived at the same time. The Doctor was mistaken as one of the delegates, and Sarah went to go sunbathing. There, she overheard two Chelonians discussing how one had poisoned the emperor's drink. Sarah went to warn the delegates, but the guards would not let her pass. The Doctor noticed the emperor's strange actions and poured a bucket of water down the emperor's throat, thus removing the poison. Changing out of his now-ruined shirt, the Doctor and Sarah left Florana again to return to Earth. (PROSE: The Hungry Bomb)

The Eleventh Doctor took Clara Oswald bathing in the bubbly waters on Florana at a time when the beaches had begun to attract a large number of tourists that were causing disturbance to the Teuthida that lived in the lower levels of the sea. (COMIC: Creatures from the Deep)
