Item from Percy Jackson by Rick Riordan
The most powerful weapon in the Olympian arsenal — a cylinder of divine lightning that was stolen in the first book, kicking off the entire series.
The theft of Zeus's Master Bolt is the inciting incident of Percy Jackson — a cylinder of crackling white-blue divine lightning compressed into a solid form that hums with enough power to level a city. Ares stole it (manipulated by Kronos through a dream), Percy was framed, and a twelve-year-old had ten days to return the most powerful weapon in mythology before the gods went to war and shattered Western civilization. Percy succeeded through luck, loyalty, and a willingness to mouth off to gods, but the theft exposed the fractures between the Olympians that Kronos would exploit throughout the series to turn their own children against them.
A two-foot-long cylinder of crackling white-blue lightning compressed into a solid form. It hums with power and the air around it smells like ozone. Holding it feels like gripping a thunderstorm.
Also known as: the Master Bolt, Zeus's lightning bolt
