Ballad of Bergharuth

From the description: Rumours brought you here. Tales of an ancient demon prince. Demonic tunes from his flute make the earth tremble and crack open, revealing terrors previously unseen. For followers of the Two-headed Basilisks, his existence is a threat to their belief, values and knowledge of this world. To others, he is just another deadly force here to end the world. Ballad of Bergharuth is a supplement for MÖRK BORG and was designed for the Bad-Basilisk Berg-Borg Jam. It contains a scenario to build an adventure around, a description of the demon Bergharuth and his deadly thorned root-like tentacle spawns.
