You may also have acquired a great deal of magical or martial knowledge and power. No living person except the natives of The Void will ever be able to fully understand it.If you survive a Void trip, you will almost certainly have acquired a greater understanding of the whole Universe, and the essence of existence itself. It is more like a dream world, where anything can happen. The Void does not have any clear ends, it is just infinite, at the same time it isn't. But what is known, is that The Void is a plane of magic beyond common wizard's or prophet's minds. If that's true is not known for sure by anyone, except the natives who have always lived there. Some prophets claim that The Void is the Realm of Souls, Plane of Nonexistence.

If your body dies, then you remain in The Void, until someone eventually summons you. If you die in The Void, your body remains in that state until it dies of natural causes. The remaining body of yours can't drink or eat by itself, only breathe. While in The Void, your soulless body remains in an immovable, unthinkable state. When you enter The Void, you have to go through a ritual that sends you off. Few people have ever been to The Void, and even fewer have returned. It's existence is not common knowledge, but it is spoken of among most races and cultures. The Void is a far and distant plane from most other known Planes.
