This witch vampire is trying to incorporate the aspects of the elements within her. So far, she has succeeded at incorporating the element air to her being, which has given her wings. She bears a bow and holds a red arrow in her left hand. She has bitten her right wrist and put the blood into the cup and now she is pouring it in this flaming cauldron. I think this time she is working on the fire element and trying to make a concoction she could drink to incorporate fire within her. There is a skull on that cauldron of hers with a reversed heart on its forehead. Also, I can see skulls on the left side of the cauldron very lightly but the effect is there. Now that she has started this process, an entrance to a new level of understanding has opened for her in the background.
