Pedro was a scribe to King Bryon in the post-Burning kingdom of Canoga. While doing research into ancient texts, Pedro came across a device called a Gatling, which could spit bullets in rapid succession. Although Bryon didn't initially believe the reports, after Pedro showing him a picture of the device, Pedro was allowed to pursue its manufacture. The creation of the Gatling allowed Canoga to overtake the duchy of Pacoim.
