The Burial Mound of Gilliard Wolfclan

From the introduction:

Old Tooley Tells you...

“Way back when, the barbarian chief Gilliard Wolfclan trucked with evil spirits and went mad. His clan killed him and buried Gilliard and his followers in that there mound, sealing his evil away. Seems to have worked so far. Anyway, there's been weird noises comin' from inside the mound lately. Maybe you heroes should check that out. I hear old Gilliard had himself a magical sword, but I don’t imagine that interests ya'.”
