This sign was used by bouth Supreme Master of The Dark Side and Dark Lady of Sith Darth Shadow and the crime lord known as The Shredder. In the SW world, the symbol was used during both of the Shadow Eras and The Great Shadow Wars. In the TMNT world, the symbol was used by all The Shredders that ruled any part of the world.
The build itself is not that big, being only 20×20 studs in size. It is a good display set, very much resembling the building style of the LEGO ART sets.
