Summary of recent events...
The Dwarves knew the caves were bigger... Bigger then any before in recorded istory. They seemed endless in size, yet Dwarves are never happy till all is explored and under Dwarf Law.
The Law of the Dwarf after all was what they minned, they owened, and that applied no matter how far down they went. But how far was too far? Dwarves knew that going down was dangerous. They all knew the tales of not "delving too deep" Of not going beyond the fabled Magma Sea that was said to warm the world.
Yet here, in the deepest cave system ever encountered, there seemed no limit to how far down they could go...
At a distance nearly 3 times that of where the Great Sea was across the rest of the world, water still flowed and Tower Caps could still be found.
The outside world was but an after thought, the freezing winds of year round winter was forgotton as deep below the Dwarves labored away. They had discovered the great Blue 'living metal" and had become consumed with it's riches. The most powerful forts in the world could dig only a small fraction before they had to stop, less they 'Delve Too Deep" But here... Here the Great Living Metal seemed to go on forever. Lured by riches beyond comprehension, they dug down and down, heedless of the ancient warnings.
Over time however, the world seemed to turn on them. The great Magma Pipes they used for smelting began to drain away... Month by month they had to dig new foundries to follow the lowering magma pipe. It seemed as if the Earth itself, angery at the plundering of it's wealth, was trying to deny to them it's hot blood. But Dwarves do not let such things stand in their way...
Capturing great amounts of Magma in a vast cistern, they went on, forging a wealth of 'Living Metal" such as the rest of the Dwarf World could not have ever imagined. The small fort became forgotton in time. Less then Fifty called it home, it's location on the freezen southren mountain kept all invaders away. The fort expanded, the people grew drunk from it's riches, and the magma kept sinking...
Year after year passed, the Sea fell more. Rather the question such an event, The Dwarves dug ever deeper, carving out into the vast cavities now left uncovered from burning rock. The depths they dug became as unfathomable as the riches that bloated them...
And then, then at last they saw it. Saw where the Magma Sea was going...
Nearly 200 "levels' bellow the mountain, they saw a vast whirlpool of burning rock. As if someone pulled the drain upon the world. They saw the burning rock pouring down into an abyss, an abyss of darkness such they had never seen before.
They looked into the Abyss, bloated, fat, covered in riches of living metal, and they heard the screams begin...
