[@Meta] Basically, the darkness is the body and it's will is a point of blood. The blood can move freely through the body, carrying that special point of blood with it, but only muster the body part which is directly in contact with that point. So i can basically use it as a freeway through the dimensions and such but only harness the power of the surrounding darkness.

The way I phrased it, I only had in mind transportation and way of movement through dimensions. Maybe I shall word it differently?
