Kabuki

 was a specific mountain on the planet Tora. It was home to the hermit Ly-Chee for over 30 Toran years. Towards the end of his cave-dwelling life on the mountain, Ly-Chee met the Seventh Doctor, who had long heard Kabuki described as the best place in the whole of the Crab Nebula for peace and quiet. The Doctor stayed on the mountain for several weeks, until he accidentally ended Ly-Chee's life of contemplation and started travelling with the ex-hermit in the TARDIS.
