Things exist, and the ants scurry around every day trying to justify it all, but there is no real reason why we do it. Those with the proper disposition can project their desires into the Void and impose their own meaning on reality for a short time. Space is simply a way for the ants to simplify the Void, a trick of denial. Decay hits everything, including the ants' nice prepakaged beliefs, which is why they don't like it. I mean, it's cool to be, but to be does not mean that you be something.
Stuff exists, plain and simple.
Just play with existence and see what kind of pretty toys you can make. Thoughts impose pattern on the Void, trying to make sense of the utterly senseless. Play with the ants' thoughts, screw up their pretty patterns, and watch 'em go nuts. It keeps Existence from falling apart too quickly, keeps the Power running, and keeps the ants breathing. Spirits reflect the light and dark of the reality the ants are desperately trying to create, and show us what can happen when you deny the truth of the Void for too long.
