Stark Triton, a veteran activist of the Universal Primate Captivity Crisis movement at The College of Mercury Retrograde, has been on several primate retrieval operations in the 22 years since earning their Hyperspace Doctorate. Having long lived by the tenets of Doctor society, Stark decided to join the cause of the Critical Earth Expedition for the benefit of the primates. Now, with the fate of the Earth primates in the balance, Stark and the Doctors will do what is needed to liberate them from their captivity.
