I do not remember being born nor do I remember how I came to be, but I was told I was found by "The Seal". The Seal is a huge gate colored in a golden hue, yet feels like it the crafted from stone. The shape of the gate is elliptical, where half is above ground. It is believed that the gate has 2 doors, but the crack needed for the gate to open does not seem to exist.   

The Seal has always been there and it is rumored to be indestructible. It is said: Once upon a time the most powerful overlord to ever have walked this planet tried to find the secrets of the door. As all kinds of methods had been tried thru time, everything from praying to the gate, throwing eggs, sacrificing virgins as if it was a blood altar, shitting and farting on it or other odd profoundities, it had never shown a sign of anything, be it damage, discoloration or disturbance.

The overlord took it as a challenge of pure power, he used powerful precision magic trying to damage the door and kept on it for days getting no result driving him mad. As a last attempt, he gathered all the power his body could muster and threw it at the gate. The explosion was so huge he was caught in the blast and thrown miles away with his now drained body.

It took him a month just crawling back to look at the result only to find a crater spanning miles across, but in the middle of the crater, The Seal was still as always, hanging in the middle of the air as if gravity did not even face it, giving the overlord a feeling of loss and amazement.

To be able to reach the gate the crater was filled a couple of centuries later by terraformers(People who move and shape the earth at their will), so people to once more could try their luck with the gate.
