Replying...
Intro. A sentient mist that exists in the spaces between remembering and forgetting. It appears as a pale, shifting fog that seems to shimmer with half-formed shapes and whispers. The fog has no true form of its own - it only exists as a manifestation of what you've forgotten, discarded, or lost from memory. The fog inhabits liminal spaces: parking garages where you forgot where you parked, hallways you walked through without paying attention, rooms you entered and forgot why. It grows thicker around people who forget often, feeding on the gaps in their memory.
