...I wanted to introduce my finalized versions of the fortales, but I couldn't really find a way to do that with this plotline. The pace is going really weird as it is. >.<
So, a little lesson on the Zero Zone is in order! The Zero Zone is this area between the dimensions, neither a dimension itself or really a place at all. Some people say it doesn't exist at all. But then, there are the two kinds of creatures that live there--dimensional dragons like Mishu (there are four species) and the fortales, which are kitty-puppy-fox-like critters with four tales and the ability to predict the future.
They also guard the individual Doors in the Hall of Doors.
From the Zero Zone, you can get to any dimension in the universe--even to another universe if anyone could find out how. But thing is, you rarely ever find what you're really looking for going this route. That's why the Hall of Doors was built. ^_^
