Ekthelios

From Tardis Wiki, the free Doctor Who reference

Ekthelios was a planet with a spaceport patrolled by GateBots. The Eleventh Doctor and Amy Pond had a dangerous adventure there, in which they prevented Ekthelios from becoming part of the Croidum Expansion. The Doctor and Amy were recognised as heroes and granted the freedom of the planet by the Central Governors. (COMIC: Attack of the GateBots!)
