How it came to be

Dural Stuk'daril was created by a Meteor crashing down on the planet of Aslumar. This caused the entire area of Dural Stuk'daril to form within the blast crater. As the hot rocky surface cooled, the ground became mountainous, and slowly filled with water. This in turn created a series of islands surrounded by a steep mountain range in all directions.

When the Meteor struck Aslumar, a large amount of magical energy was released. This energy pooled together and created a pocket dimension. It created an area in time and space that existed on the planet, but outside the dimension of the rest of the world. To anyone who traveled to where Dural Stuk'daril used to be, there was nothing missing. There was no gaping hole where the meteor hit, it was like Dural Stuk'daril was never there. To Aslumar, the meteor never hit.

This pocket dimension however, is a magnet for portals. All who try to teleport through the area which used to be Dural Stuk'daril were then pulled into it. This includes those portals and teleportation spells used to leave the pocket dimension. Those who come, are never able to leave.

In continuation with the large amount of energy that created this pocket dimension. This energy eventually collected, and cooled, and in its wake, a conciousness was born. This conciousness was a being of pure energy. It could shape the small world in which it was created any way that it desired. It could move mountains, reshape creatures, create live, and deny it to others.

This conciousness was curious about its own existence, and it was alone in the cell that it couldn't leave. Over time, it became more and more comfortable with the power that it had, and created itself a companion. Essentially the entity split itself, and its power in twain to create this other one of its kind. For a time, they were content and happy with being in their prison. They created many wonders, and had fun with those who came to reside in their own little world.

But how long can a being with almost unlimited power continue to be "equal" with another, when all others cower in fear of your power? As time progressed, the second slowly grew to despise the first. They broke out into all out war, and they created vast armies, with various tools and weapons to destroy the other. They made massive cities of war, and tools of destruction. Many millions of lives were lost as these beings fought eachother. Technology saw no equal, and magical abilities were beyond compare.

It eventually came a time for the two of them to meet in battle, after wasting millions of the followers they created for their pointless war. Perhaps their war was the spawn of boredom, but the end result was still the same. The two of them fought, and they were both wounded, greatly. There was a huge explosion, and all of their massive cities, and towers of technological advancement came crashing down to the ground, and sank into the sea.

Neither of them died, but the explosion used the majority of both of their power. They are still immortal, but that does not mean they can be unharmed. There are still several ruins laying across Dural Stuk'daril which resonate with the power they once had. All of these places of latent power and energy lay untouchable by them, those beings which have power, but not enough to be recognized as who they truly are.They each sit silently in another hidden location of Dural Stuk'daril, waiting, watching, hoping for the time that they can eventually strike down their enemy which was once a part of them, by using the same creatures that they destroyed countless numbers of in their fruitless war.

To continue on about the meteor itself.

This meteor was not just some normal ball of rock hurtled through space at some hapless planet. This ball of rock, chock full of magical goodness, was the corpse of a God. A God died in one of the other planes. It floated around aimlessly in the Plane. Eventually, a group of its followers collected together and started to do a ritual of re-awakening. To cause their dead God to come back to life. What happens when one messes up with this ritual?

A tear in the plane was created, sucking the God through it. It was then hurled at the world, and everything that happened, well, it happened. This was why the meteor had so much magic, this was why so much energy was released when the corpse hit the world. This was why the crater was so large (1800km x 1800 km), and why havoc ensued.

The entire purpose of this campaign (other than for the players to have fun), is for one of the God-like, non-Gods, to consume the other, and the rest of the remaining energy in Dural Stuk'daril, and become what it really needs to be, a God.
