The story before this adventure began 

The party of heroes, who were on their usual adventures, rushed off immediately upon receiving an urgent request from the Guild for help.

The guild had a request from a novice adventurer, but that request had a particularly unresolvable problem.

The objective of the quest was simple exploration, searching, and collecting location information, making it suitable for novice adventurers. However, as many adventurers lost contact or went missing while proceeding with the quest, the difficulty of the quest was raised to the level of advanced adventurers.

The hero's party could not let this matter slide, so they accepted the request and set off on a journey.

Upon arriving at the location, the party of heroes investigates the surrounding area in accordance with the purpose of the request.

However, as the investigation continued, nothing strange was found, and we ended up going deep into the valley below in that area.

  - As I was entering, a question arose in my mind: I could not find any traces of the other adventurers who had been here before while carrying out quests.

Just then, the hero's party was caught in a vortex of unknown black magic and ............................. disappeared.
