Vitalia

Foul occult magic, rare alchemical reagents, and copious amounts of spilled blood are the keys to creating a vitalia-also known as a heart horror-though thankfully the exact means of their creation has been long forgotten.

Now, most vitalias now come into being by sheer accident. This unusual life-form cannot live without regular contact with blood, much like how fish cannot live long outside of water. Because of this, vitalias are rarely found outside the lairs of mad alchemists or wizards, living in pools of the life-giving substance. Physically, a vitalia somewhat resembles a blood-red giant jellyfish, though it also bears some semblance to a giant human heart.
