Story
Although they were believed to be mythological creatures, the existence of Gargoyles was discovered shortly after the first expedition to the geologically unstable underworld. At first they seemed content to remain in their subterranean realm, but recently they have begun to appear in our world as well, seemingly with the goal of causing us great harm. These diabolical enemies have begun to take control of our sacred shrines and places of enlightenment. Dozens of houses and villages in our country have been destroyed in night raids by the demonic fiends, while countless others stand empty and abandoned. Local and state militias have organized to resist the ominous invasion from below. Entire brigades of experienced warriors from Serpent's Hold have taken on these tireless foes on the battlefield, but to no avail. The Gargoyles' methods suggest that they are in search of something very valuable. It is even rumored that they seek your destruction, but why this is so we do not know.
