An Earth-like planet was the homeworld of the Ethereals. It had a thin atmosphere and its surface was covered by a spongy grass-like material.
The First Doctor arrived on this planet and was captured by living clouds. He learned that they were Ethereals, who had been turned into clouds by their former servants, the Baggolts. The Doctor restored their original bodies and helped them put an end to the Baggolt rebellion. (PROSE: The Cloud Exiles)
