Grandport Sewers is a location in Octopath Traveler and the dungeon of Tressa's final chapter. Here, she chases down Esmeralda to reclaim her stolen notebook.

Description

Grandport Sewers is an aqueduct flooded with shimmering water, shafts of white light, growing vegetation, and crystalline waterfalls. A ship floats in the background, while crates, barrels, and loose planks line the path. The dungeon's boss room unveils a dramatic plinth surrounded by white pillars, backlit by a line of foaming waterfalls.

Trivia

• According to the merchant near their entrance, the Grandport Sewers are used to transport wares to the auction house. This may explain the giant ship moored in the background of the aqueduct.
• Grandport Sewers is the only non-cave dungeon in the Coastlands.
