planet (disambiguation)for other, similarly-named pages.
On the funeral, a Cwrier gave the Eleventh Doctor an invitation, in the name of a "lifeform unknown", which led the Doctor and Alice Obiefune into a planet with a lot of trees, so high that Alice compared them to skyscrapers.
The Doctor told Alice he had visited the planet a year before, and that, on this occasion, it was predominantly a desert planet. Back then, a humanoid species inhabited the planet.
However, when the Doctor returned to the planet with Alice, all the several million individuals from the species were gone.
