SteN, Drakkosha, L@R$$ON, you are registered. The map is called "Black Square" because... well, it's a black square. ;)
To be honest, I initially wanted to come up with something more elaborate, like "Land of Despair" or something similar, but then I decided that this is great too! :D At first, the map was completely black - it looked nice, but there weren't many objects, and it wasn't very diverse. But it's perfect for a stage for the Death faction!
Good luck and all the best!!!
