Perhaps it’s just me, but I would never have imagined that LEGO Power Functions and LEGO Castles would go well together. There may be other examples out there that I am not aware of, but Marco den Besten (Ecclesiastes) proves me wrong with his Acirhon’s Nest.
At a first glance it’s a decent-looking castle with a bit of a fantasy theme. Take a closer look, however, and you’ll note a moving representation of a waterfall, a bear that moves in and out of its cave, some sort of bat circling one of the towers and warriors emerging from hatches in the top of another tower. Powerful stuff.
