By The Power Of Whiteskull! Grantmasters has the Power! Or he certainly appears to, based on his latest piece of LEGO microscale building. The skull sword hilt is put to excellent use here, and its textured elements give an impressive sense of depth and scale to the tiny castle’s entrance. However, don’t miss the use of skeleton legs, wheels, and a good old-fashioned LEGO maxifigure’s arm in the creation of the rest of the keep’s towers.
