Cool idea Lauder. Could you do anything with the 'source' of the river? I'm assuming it's not actually water in the river?

Nope, not water but instead blood. The wound closes itself every now and again or it ruptures again. The source, it could be like a deep cut in a mountain. Though, I never put much thought into that.
