Missing ingredients are common quests in game-oriented and narrative worlds where characters are tasked with finding some missing or misplaced item needed to complete a recipe or blueprint (potions, antidotes, spells, broken machines, and stews are all commonly in need of a missing item). Typically, these quests involve traveling to a known location or known general region and searching for the missing ingredient. The journey to this location may be dangerous, and may involve perilous bridges, cliffside pathways, or dangerous terrain hazards. The location itself may be unsafe, with things like lava flows, geysers, flooding, or other events occurring. There may be hungry beasts about.
