"'How do I have his blood?' I asked him. Plain and simple. As for why I'm spilling it," she gestured to the array underneath their feet and explained. "This is a [Cause Tracking Array]. Using it we can find a person; their exact location, status, and even scry at their past and present."
Emptying the fourth and final flask, Ka'lor'ah threw the empty container outside the bounds of the array. She then stamped her feet on the pool of black blood and instructed.
"Now, be a dear and move outside the array. This formation is very temperamental and I don't want to see it fail."
