A10%?

The Doctor watches a trap go off among a group of paradox-evolved Voord. (COMIC: Four Doctors)

A10%? was a year of the Last Great Time War. The Daleks attacked Marinus in this year. The War Doctor created a Paradox Shield to protect the planet from their attacks. At this point in the war, Marinus as well as the native Voord had been drastically altered by the paradoxes and changes in history caused by various timelines being overwritten repeatedly.
