Alien Worlds
Delta 3

Delta 3 is the third of Delta Magna's moons. Most of the planet is a swamp, with reeds as big as the TARDIS. The native inhabitants are classed by the colonists as Swampies.

As Delta Magna has become greatly populated, a methane refinery was set up on the third moon, much to the resentment of the Swampies.

The fourth Doctor and Romana visited Delta-3 in their quest for the Key to Time, and become involved in a conflict between the colonists and the Swampies, who were armed by the rogue Rohm-Dutt. The Swampies worshiped a giant squid, Kroll, which turned out to be the fifth segment of the Key to Time.
