This set contains 20 dice designed to look like Necron artefacts. The 1 faces feature a leering Necron skull. Faces 2-5 have pips connected to each other and the other faces of the dice by pipework. Replacing the 6s is the Ankh of the Triarch, symbol of the Silent King's authority over all of Necron-kind. Each dice measures 16mm and is square-cornered. The outer shells are silver/grey metallic colour, with recessed green plastic that makes them appear to glow like Necron technology.
