Galspar

From Tardis Wiki, the free Doctor Who reference

The colony planet Galspar produced the universe's finest ice cream. The I enslaved and brainwashed most of the planet's population, and injected an experimental solution into Galspar's ice cream that transformed humans into I.

There was only one major city on Galspar: Christopher Columbus. The rest of the planet was mainly covered in fields where cows were kept for milk. (AUDIO: I Scream)

The Doctor once battled the Klade on Galspar. (PROSE: Father Time)
