Shadow Walkers are a strange breed that possess the ability to slip between the planes of reality, becoming immaterial. This allows them hide in the shadows, either hunting from the concealment of near invisibility or evading enemies. Though they become corporeal to mate or to eat, they spend most of the rest of their lives walking in the shadows. Shadow Walkers are wary creatures, though on dark Autumn evenings when the leaves fall to swirl in the chill, rain damp air, they may be seen drifting out from the shadows.

Phasmati has no conscious knowledge about where she came from. For as far back as she can remember, she has always been alone.  As a result, she has lived a very lonely existence.  That is, until the day she crossed paths with Corpsebeak, when the Black Marrow happened to come across the wild boar Phasmati had recently brought down.  Immediately, Phasmati felt a mutual connection to Corpsebeak, and from that day on, she has accompanied Corpsebeak as he continues to travel with Carnelian Shadow.  While Carnelian Shadow is unaware of Phasmati's presence, Corpsebeak is always fully aware that she is nearby, and the bond between the two only grows stronger with each passing day.
