A lingering force was a subtle form of spirit that persisted after death, yet never coalesced into the unified shape or identity of an Undead creature. Unlike Ghosts or similar manifestations, a lingering force did not necessarily contain an entire soul. Instead, it was believed to be a minute residue of will, intent, or power that detached from the greater spiritual whole during death or dissolution. These remnants often arose from moments of intense emotion, purpose, or sacrifice, and they reflected only a fragment of the individual they originated from, lacking full memory, personality, or self-awareness.
The capabilities of lingering forces varied widely depending on their strength and coherence. Weaker manifestations were little more than impressions, capable only of conveying sensations, emotions, or brief messages. Others possessed limited intellect and could respond in simple, repetitive ways tied to their original purpose. Stronger lingering forces were rare, but they could impart energy, bolster resolve, or even channel magical power into the living. Such entities were often bound to locations, objects, or circumstances closely associated with their creation, and they gradually faded as their remaining energy was spent or dispersed.
