Royal Waterways

A series of sewage pipes and support structures underneath the City of Tears. At the east end is a lift shaft to the City that has been destroyed. Near the northeast end is a shaft connecting to Eternal Emilitia's room in the City of Tears.

Sub-area: Isma's Grove
''Only those who prove their honour in combat may enter the grove beyond. - The Defender''

A hidden garden accessible by using Crystal Heart to dash through a tunnel of spikes at the east end of the Waterways after defeating the Dung Defender, or through a tunnel connected to the Kingdom's Edge. The Grove houses the presumably deceased Isma, on whose corpse the Knight finds Isma's Tear, which allows the Knight to swim through acid.

Sub-area: Junk Pit
A massive cavern filled with Geo chests, paintings, a Monarchfly statue and assorted piles of other trash washed up by the currents. This pile of rubbish is said to be Flukemarm's treasure by Fluke Hermit who is also found within this area. Though among all the worthless junk lies a golden sarcophagus which when opened by a Simple Key reveals The Godseeker where they have been hibernating. Accessible by breaking a roof on the top left corner of the square-like area next to Flukemarm's boss room. A wall at the top of the Junk Pit can be broken up to reveal access to the City of Tears, below the Nailsmith's forge. If the Nailsmith is killed his corpse will appear afloat the Junkpit waters, near the shore.

Trivia

 * There is an unused key in the game's files labelled "Waterways_Key" which was presumably used to open Royal Waterways instead of the currently used Simple Key.
