Linn traveled through time and became a down-and-out heir to the Blackthorn Territory. The territory was barren and riddled with debts. His only "legacy" was the former lord - the "magic machine" that his ridiculed father was obsessed with researching. Everyone said it was a waste of gold coins. Until Linn polished the faint light in the eyes of the rusty metal puppet in the cellar filled with scrap metal. The rusty gears, the weird drawings, the half-finished mechanical core deep in the cellar... This soul from another world will use iron and fire to walk a completely different path in this world of swords and magic.
