Blood for the Serpent King

From publisher blurb: A Level 2 Adventure Deep in the jungles, amidst the ruins of an unimaginably ancient civilization, dangers lurk: feral tribes and predatory beasts, and darker things that civilized folks prefer to forget. You’ve heard the rumors of the treasure hordes of one of those great evils: the legendary serpent-man, Xiuhcoatl. They say that Xiucoatl is worshipped by feral tribes of degenerate serpent-men who call him The Emerald Cobra. Do you dare face their rites of blood and sacrifice?
