The LEGO Hidden Side 70427-1 Welcome to the Hidden Side set introduces the augmented reality universe of Newbury, a fictional town where physical and digital ghost-hunting merge. This 189-piece model centers on a brick-built spectral portal structure, featuring interactive rotating elements that activate distinct events within the free LEGO AR app. Viewing the set through a smart device reveals a ghostly world, enabling players to hunt apparitions and confront the boss ghost, Lady E. The set includes four minifigures, ready for exploration and mystery-solving within this ever-expanding digital realm. The distinct portal frame, constructed from various plate and brick elements, forms the central hub for triggering these AR interactions and exploring the haunted Newbury landscape.
