With no confirmed single source attached to this upload, the sound is used online mainly as a generic dark summon cue for edits and fan projects. Short dramatic summon effects like this spread through soundboards and video edits because they can label any entrance as important without showing the original scene. Creators reuse it for boss spawns, gacha pulls, card reveals and roleplay moments, where the rising dark tone does the storytelling in under five seconds and works even on mute-off, quick-scroll feeds.
