Urlic

Urlic was a barren desert planet in the Catorkian Galaxy, Starkey remarked that it's air smelled of rotten eggs.

Sometime before 2050, it became the last planet in it's galaxy. Due to it's endangered status, it was archived by the Ukkans into a Library card. However, it was taken from their archives by Huskian pirates. Eventually the card found it's way to Earth and it was acquired by The Department. As there was a prison over-crowding problem on Earth in 2050, Inspector Thorne decided to turn into a prison colony and just dump prisoners there. (K9TV: Lost Library of Ukko)
