Observation: Predator

Observation: Predator is a memory found in JasKra's chamber during Heart of Stone. It is combined with Observation: Focus to create Combined observation: Ariane and the golem.

Reviewing
As the vision swirls into focus, you see Ariane constructing a magical device. It seems to be some sort of tracking machine and you can tell she intends to use it to hunt down Xenia.
