The Heart of Darkness (Patreon)

Your party begin following the path of destruction left by this red object. Your parties wizard is unable to discern the marking, but notices the magic within is nothing he's come across before. 

Nearing a clearing, you hear the sounds of someone speaking a litany of heretical phrases. And soon you see a battle ending with a human being stabbed though the chest by an unspeakable horror. A giant heart with crab legs and whipping tendrils. Dispatching its foe quickly before Turing towards you. Without ceasing its speech, it charges forward.
