Captain McCallery voyages to a planet of prehistoric monsters in search of a reclusive Weaponmaster.

Space Pirate Captain McCallery needs a Weaponmaster to round out his new crew, and he knows there's only one man for the job: Mark Two-Blasters. A former member of his crew, Mark Two-Blasters left a year before the rest of the crew mutinied, due to disagreements with some of the other crewmembers. He took a shuttle and flew to the planet Ograr III, one of the most dangerous planets in the sector, to spend time training in isolation.

Ograr III, a planet of prehistoric beasts. Ograr III, a planet of thick forests and high mesas. Ograr III, where Mark Two-Blasters has made his home for the past year.
