Locke, the illegitimate son of King Bulgher of Botica, was born to an unknown mother in the southern dark realm. Exiled alongside her to the wastes, he nurtured a seething resentment toward his father and half-brother Kelby, which hardened into a vengeful obsession. In an age where magic was thought lost, he defied this belief by mastering sorcery and forging a pact with Mora, the eldritch Essence of Magic, to seize power and hunt the "Last Heart"—a legendary artifact tied to Gearbolt’s hidden truths.

Declaring himself the Mystic Emperor, Locke spearheaded a swift coup against Botica, deploying armies and colossal War Golems to topple the kingdom in a single night. He personally slew King Bulgher during the assault, securing his tyrannical reign. His operations relied on the Fraternity, an elite cadre of warriors—including Dex, Bridge, Manic, and Coin—who blended advanced technology and sorcery to execute his schemes.

Locke’s magic granted him levitation, flight, memory extraction, and superhuman strength, augmented by an uncanny ability to infiltrate and dominate robotic systems. Mora’s dark influence amplified these powers, though the price of their alliance stayed shrouded.

His vendetta against Kelby spiraled into a relentless campaign, marked by assassins, War Golems, and the dreaded Cannon Busters hunting the prince. Though a cunning strategist, Locke’s fixation on vengeance and dominance often eclipsed caution, triggering violent clashes with adversaries such as Philly the Kid and Sam.

His story weaves themes of betrayal and ambition’s corrosive toll. As a scorned heir, his brutality and manipulation framed him as a tyrant, yet lingering questions surrounded Mora’s hold over him and the fallout of their pact, leaving shadows over his legacy.
