A long time ago in a far away land there was a castle the peasants called the crt. It was great but soon it was too small for the growing hordes of dots and so the king called to the lands for workers to make his kingdom larger and thus came for the pix'ies. They waved their wands and rows upon rows of individual dots came forth. This too wasn't enough as other kingdoms sprouted forth with their castles and soon there was war between the castles all trying to make bigger castles. Some kingdoms were destroyed others were anew. The workers in the new castles were too slow and so the vp's came forth and build machines that worked together to make the workers work faster. But it still wasn't fast enough so the Kings keep pushing their workers to build faster and faster machines.
