the chroma
Haunted by the guilt of abandoning his younger brother, John embarks on a getaway in the Canadian outdoors, where he encounters the Chroma, in the form of a tree with a bloodshadow. The Chroma latches onto John's guilt like a parasite. 
   
The Chroma cannot be seen while its bloodshadow is visible and, conversely, the bloodshadow cannot be seen while the Chroma is visible. Characterized by such contradictions, the Chroma generates reactive panic.
   
Capitalizing on everything from the habitant predators to the traitorous member of the group, the Chroma strives to achieve its unprecedented purpose -- to sever the bond between brothers with the use of deception but without the use of coercion, to patiently acquire the demise of the senior brother.
