Biography
Astrolabus was banished from Gallifrey. He stole some star charts from Voyager by travelling to Antarctica and threatening the Sixth Doctor with a gun so that he handed them over.

Astrolabus fled, with the Doctor giving chase. Astrolabus escaped in a Da Vinci original flying machine. Returning to his TARDIS, which was in the form of a lighthouse, Astrolabus told the Doctor how he had helped Alexandria develop into a crossroads for aliens. The city grew great under him and he helped build the world's first lighthouse there.

The Doctor identified him as the thief who stole the book, and that he had plundered treasures before the Doctor was even born. The Doctor called him a pirate as well as a thief. Astrolabus made the Doctor imagine he was falling from the lighthouse when he was on the ground, gripping the edge of a table. The Doctor escaped and Astrolabus pulled a lever atop his lighthouse. It turned into a rocket and took off. (COMIC: Voyager)

As Professor Astro Labus, he set himself up as president of the Zyglot trust, while as the swami Astral Arbus, he employed Akkers to capture Zyglots. When the Sixth Doctor and Frobisher caught up with him, he pulled the Whifferdill with him into his cabinet. (COMIC: Polly the Glot)

Astrolabus had the stolen star charts tattooed onto his body. The Doctor tracked him down and captured him. Voyager then retrieved the charts by removing Astrolabus' skin, leaving him to die. As the Doctor left, Astrolabus called out, "How can you know how long I've been writing your life? What will you do now that I'm gone?" (COMIC: Once Upon a-Time Lord) He was rescued from this predicament by two individuals from his past (PROSE: White Canvas) and recruited by Faction Paradox, becoming Auteur. (PROSE: Going Once, Going Twice)
