A strong warrior arrived in the human capital, and approached the leader's abode. As they advanced, they were challenged by soldiers, which they ignored. As they neared the leader, guards attacked them, but the weapons passed through them with little resistance, no visible damage done, and nothing to show for the effort but a dark slick across the blades. The stranger stood before the human leader and spoke. "A force of evil approaches this world. It will destroy all if it is not stopped. You must prepare to face creatures of great size, terrible magics, and radiant evil that will sap the will. Build a fortress, and raise a force to defend it." The stranger then turned and left, disregarding the humans until it vanished into the shadows beyond the city.

A great disturbance rose in the depths of the ocean. A great mass of earth emerged from the depths beneath the floating continent, filled with twisting passages, great caverns, and expanses of water or magma so vast that they could be considered oceans in their own right. It was unclear how deep it went, nor what bizarre environments it might contain, but there was room for whole civilisations within it. For now, however, there was no life there, beside the insects...
A great horizontal plane of energy appeared within the floating continent and within the mass of earth it floated above,, it slowly descended into the mass, and passages were forced into it, and forced themselves into the floating continent. Most stopped short of the surface, but in a few locations a passage reached the air, and allowed access to the world below.
