Mordee

An Earth-like planet had at least part of its surface covered in dense jungle. The Horda were one of the native life forms.

In the far future, the planet was colonised by the Mordee expedition. Shortly after they arrived, the Fourth Doctor visited and assisted them in repairing their computer, Xoanon. Centuries after his original visit, the Doctor returned to the planet, only to find that the Mordee had split into two groups, the Sevateem and the Tesh, both of whom worshipped Xoanon, who had gone mad from the Doctor's efforts to help. After restoring Xoanon's sanity and reuniting the two tribes, the Doctor left, accompanied by the Sevateem warrior Leela whom he had befriended, and who had helped him survive the Sevateem's attempts to kill him because of a case of mistaken identity. (TV: The Face of Evil)

The planet had giant jungle birds, (AUDIO: The Time Vampire) no seasons, (AUDIO: The Child) and cave frogs. (AUDIO: The Man at the End of the Garden)

Leela once compared the Congo in Central Africa to her planet. (AUDIO: The Ghosts of Gralstead) The jungle planet Garros also reminded her of her home planet. (AUDIO: Zygon Hunt)

Leela once told the Brigadier that her planet either had no name, or the Doctor never told her its name. (AUDIO: The Revisionists) A version of Leela from an alternate timeline referred to the colony world she came from as Mordee. (AUDIO: Disassembled)
