I used Lady of Darkness. 

It has lots of dark elements with hints of blood. A dragon, rats, skulls, owl, bats, lightning, and so much more to play with. It contains 90 Elements, 10 Papers, and 10 Frames. This kit is an exclusive kit to match Trinita's Tube Lady of Darkness.

You can purchase the kit at the following stores:
