The Prospector is an alien working for The Consolidation, an interstellar corporation that extracts the cores from planets and sells them for a profit.
Unlike Nekross, the Prospector can be affected by magic.
The Prospector was tasked with extracting Earth's core and selling it for a profit so he made a hyper-dimensional vault in Room 12 of King's Park High and started "recruiting" the school's teachers and pupils and also an Unenchanted man named Michael Clarke in order to use their mental energy to power his pulse drill.
Later, Michael's wizard son Tom and his friend Benny Sherwood (who are pupils at the school) arrived at in the vault and were confronted by the Prospector who tried to recruit them. But Tom was beamed up to the Zarantulus by Varg whilst Benny was able to escape. After being returned to Earth, Tom (with an explosive device on his wrist which would explode in thirty minutes) returns to the vault where the Prospector tries to get him to use his last spell on him, but Tom is able to escape.
Later, Tom returns with his grandmother Ursula and Benny where Ursula uses a fairy-witch love spell on the Prospector causing him to fall in love with her. Ursula then makes a clone of herself to lure him away from the vault, giving Tom and Benny time to free Michael, the teachers and students whom Ursula teleports out of the vault with a Passing Spell and Tom leaves behind the explosive device which destroys the vault and returns Room 12 to it's original self.
After learning of the Prospectors failure at extracting Earth's core, the Consolidation beam him away from the school.
The Prospector is roughly the size of a human with green skin and bug-lie eyes. He has a mole-like appearance and wears brown leather clothes, gloves and wears googles.
The Prospector has a pulse drill that is powdered by mental energy.
