Bloody EA Pangaea: Unique Blood spells?

[Aleph]

I would love to see something like this. Pangaea with Blood pretty much screams out for the worship of Shub-Niggurath:

"Something black in the road, something that wasn't a tree. Something big and black and ropy, just squatting there, waiting, with ropy arms squirming and reaching. . . It came crawling up the hillside. . . and it was the black thing of my dreams – that black, ropy, slime jelly tree-thing out of the woods. It crawled up and it flowed up on its hoofs and mouths and snaky arms."
