Taroah was a Rock Tribe agori in the Bionicle world of Bara Magna. He vehemently opposed Tuma's rule, and paid the price in the form of a viscious nighttime ambush that damaged one of his legs and one of his arms beyond repair. Abandoned in his crippled state far from any village or trading route, Taroah was astonishingly rescued by none other than Zeyek himself. Why Zeyek chose to intervene on this lone agori's behalf remains a mystery.
Taroah was flown to a far, distant, highly advanced planet, where he was given free medical attention and fully robotic replacements for his damaged limbs. He found work on the planet and saved up his money to purchase custom-fitted weapons, including a double-barrelled blaster that would attatch directly to his right arm, as well as a rocket-propelled mortar launcher. A patron at a tavern he began to frequent has said that Taroah was preparing to journey back to Bara Magna, just days before the planet was reunited into Spherus Magna.
