Fortress of Souls

On the very edge of the realm of fantasy clichés, just beyond the furthest reaches of the Forest of Death, lies the Fortress of Souls. Its highest tower so high that the top isn't visible to the naked eye, standing there quietly, windowless. A dozen of quiet watchtowers below it, ensuring that no man will ever find out the secrets held within. The huge gate forged of the finest steel, and the river so poisonous that the mere fumes can down a hardened mountain troll a hundred yards away. Inside, the guards that nobody has ever seen, playing different variations of solitaire to ease their complete and devastating boredom.
