Are you a storyteller? Would you spin a tale? Can you pitch a yarn? Could you dream of the deepest parts of the earth, tepid and filled with the thick miasmic spores of mushrooms and intercrossed with the tangled roots of primordial trees? Drip. Drip drop. That is the sound of the rocks sweating great beads of mountain sweat onto the scattered inhabitants of the lair. Here, a tiny tribal statue; there an ancient head; both alive and dead all at once. A skeleton lies by, its arm draped upon a chest gleaming with coins and a grin on its face. Who was he? Who’s treasure does he protect? How did he come to be here? Maybe you can tell me - you’re going to tell me a story.
