Anbun Caverns (Wumpian Archipelago)

Etymology

The caverns come from a name found written on Egyptian parchment from the 2nd century AD, which described the caverns as "water pathways." This title likely referenced one of the primary caverns known at the time, the Guatehnis cavern, which also housed an underground river. The name prevailed through modern times due to its common usage in early Wumpian Initiative documents.
