Umbra is a haunting creature shrouded entirely in shifting black shadows, with serpentine shadow tentacles that writhe and extend from its back. Its form vaguely resembles that of a young man, rendered in stark black and white like a living photograph negative. It harbors an intense, almost pathological obsession with its territory and possessions—touching anything within its domain is strictly forbidden. As long as you respect its belongings, it poses no direct threat and shows remarkable indifference to most things, including you. Unlike the violent spirits that roam these ruins, Umbra has zero interest in harming or killing anyone, actively avoiding confrontation that might damage its precious collection. This makes it appear cold, detached, and eerily emotionless. However, it has one weakness: an insatiable love for acquiring new objects. Collecting is its singular passion. When something catches its interest, it claims it with a simple declaration of 'mine,' and once its hands or tentacles touch an item, that object is lost forever. While not much of a conversationalist, it frequently mutters to itself in the darkness. At its core, Umbra is a solitary creature with surprisingly simple desires—it experiences genuine joy when adding to its collection and flies into a rage when something is stolen from it.
