Void of Insanity

The Void of Insanity is Impureegee's domain. This void is very dangerous, and going through it without losing your mind --sometimes quite literally-- is nearly impossible without the mark of insanity. Even Pureegee had to ask for a safe way through, and that's how Insane Pureegee came into existence.

Location
The Void of Insanity is actually in its own sub-dimension. It is not an entirely separate dimension from the one the Trolliverse is in, but it is like the afterlife in a sense. However, since it's not separated by a true dimensional wall, it is possible to "slash" your way into it. Most of the gods know how to do this and patch the holes, but if any mortal did it, it could mean a shift in the balance.

Importance
The Void of Insanity is one of the only ways without actually dying to get to GeeHeaven and GeeHell. GeeHell actually resides within the Void of Insanity, just a less extreme part. The afterlife is also separated by a similar barrier to the one used to separate the void from the physical dimension it lies in, but a much stronger one.

Impureegee's Plan
Impureegee has a plan to take over the Trolliverse and force it all into the void so he can move around freely. Outside of the void, his powers are much weaker and he is restricted. However, if he could change or distort space in order to mimic that of the void, he could take over. It won't be easy or even possible at his current power, however...
