((OOC: Technically, Willow can't actually die, being that she's a night spirit. That's not to say she can't be harmed or weakened as she most certainly can be. If she is destroyed, depending on the nature of the 'kill', it could take anywhere from hours, days or weeks, perhaps even months to reform back into existence. So she can be destroyed, but it is only a temporary thing. With that said, her feud with Dawn's Light is an everlasting stalemate that wouldn't ever truly end. But that doesn't stop Willow from trying. Hope that helps.))
IC:
At the ghost's words, the eerie glow to her body intensifying as she became much more hostile, Willow's confusion turned to alarm then. As a matter of self-defense, she pulled the shadows more firmly around her, making her that much harder for the other to target her if it came to that. The darkness became incredibly pitch black, almost to the point where the night spirit was no longer visible anymore. Thick shadowy fingers of blackness reached out towards Raven, as if to deter her away from her threats.
"Darkness is my friend. You cannot harm me." Willow stated, voice taking on a less friendly quality now.
She didn't care if her actions frightened the eagle, as Willow's only concern right now was protecting herself.
