Ectoplasm

Ectoplasm, known as ecto for short, is the blood of Rephaim. It can be used to heighten a voyant's sixth sense and is a glowing chartreuse in color.

Description
It's a cold, viscous liquid. It has a metallic smell. When Paige Mahoney drank Warden's ectoplasm, it not only stimulated her voyancy, but showed her a path that led to his location. However, it is uncertain whether this is a common ability of ectoplasm or if this particular occurrence was triggered in part by the golden cord. Ectoplasm behaves like molten glass. If it is left for too long it will set.
