LEGO Set - 910045 - Castle - Siege Encampment

​Up for auction is a highly sought-after, limited-edition piece of LEGO history: the LEGO BrickLink Designer Program (Series 4) 910045: Siege Encampment. In original sealed brown box.

​Designed by fan-creator "Sleepless Night," this massive set acts as the direct narrative sequel to the legendary Mountain Fortress set. It depicts the Black Falcons laying a tactical siege to the Lion Knights. With only a single, limited crowdfunding run produced by LEGO in 2025, this set was never sold in standard retail stores, making it an instant holy grail for adult fans of LEGO (AFOL) and Castle-theme collectors.
​The set features an incredibly detailed medieval military camp engineered for battle readiness. It includes multiple tents for noble knights and grunts, a fully equipped weapon repair blacksmith shop, a field kitchen, and a horse/ox-drawn supply cart. Defensively guarded by narrow stockades, the offensive line boasts a massive, functioning medieval trebuchet alongside a precision strike catapult.
​To bring this expansive tactical scene to life, the set includes an astonishing 18-19 minifigures (featuring Knights, Black Falcon Archers, a Blacksmith, an Herbalist, and a Field Chef), almost all of which are entirely unique to this specific set.
​An absolute masterpiece for display or integration into a larger modular medieval layout.
