Skygrid is a map created by sethbling in may 2012.
it is formed with a map created by blocks separated by 4x4
there are chests and spawners scattered everywhere, no one can destroy and pick up the spawners although you can destroy them for exp
there is also a nether grid and a end grid
you get a skygrid inventory, not a towns and wild inventory
you can use sponges to protect builds
So that's all I got to say, bye!
