Chambers of the Fiery Heart

Publisher's blurb: Fire burns deep within this natural cave system, which gives way to man-made chambers, carved into the walls. Strange, glowing altars wait, sealed off in an hourglass shaped room. There is a writing desk covered in scattered papers, as well as a strange, blood-red gem. Deeper into the cave someone—or something—has engraved the pattern of a sinister ritual into the earth… At its heart lies a large chamber, filled with pews for worshippers. Standing on a raised platform waits a dagger with glowing gems embedded into its hilt. A giant, demonic statue with flaming eyes towers over everything.
