Joint Delving Site

The Joint Delving Site refers to a previously unexplored section of the Inverted Forest's lowest point. Its entrance is marked by a mysterious pentagonal hole.

The delvers of the Forward Expedition Party observed that there were numerous Second Grade Artifacts, further speculating if it had once housed Special Grade Artifacts. Furthermore, the Forward Expedition Party discovered a Mysterious Object in the site that warranted the immediate assistance of the legendary White Whistle, Ozen.

The site is implied to have been visited by the solo Black Whistle, Cravali, and his associate, Tepasté, with expedition leader, Hablog, suspecting a connection between the site, Cravali, and Hariyomari's Song.

Even before being surveyed, the location had created a bit of excitement among scholars of The Abyss.

Description
The site entrance is in the shape of a large pentagon. While the reason for this is unknown, it’s speculated to not have been made naturally. The Forward Expedition Party acknowledged the exceptional size of the site, going so far as to say that it would “live on in delver history”.

Lining the entrance of the site are multitudes of of the second grade relic, Forgetter.

Deeper inside the site’s interior, a round, Mysterious Object hangs from the site’s ceiling. While there is little information about what the Forward Expedition Party had found, it was consequential enough that the expedition’s leader, Hablog, immediately contemplated making the area off-limits.

Mysteriously, Funeral Tickets can be found in the site.
