Sluice Weave

The Sluice Weave is a part of Nicodranas's infrastructure and defense. There are marid and water elementals that help maintain the Sluice ducts, and can help protect the bay if it is ever under attack.

Description
The Sluice Weave is a series of tunnels that guide water from the ocean to engines within the city. These engines provide energy to businesses and other sites with particularly high power needs. There are at least three entrances to the Sluice Weave, one hidden in the city the rest in ocean. These tunnels function as intake tubes to bring ocean water into the ducts.

The tunnels are carved from stone, which is streaked with mineral deposits and has becomes slick from the moisture. This stone is also marked by the different water levels over the century the Sluice Weave has existed.

Ocean entrance
The entrance is forty feet below sea level and leads to a tunnel that protrudes fifteen feet out of the earth before it disappears beneath the docks and the city. The entrance tunnel is rimmed by a stone piece that does not quite blend in with the surrounding rock, and is a five-foot wide circular opening covered by a locked metal grate with thick horizontal bars. The tunnel runs for 60 feet before curving upwards, and 30 feet above the water line is another grate, followed by 60 feet more of tunnel leading into a square chamber.



Smaller chamber
The square chamber has a singular stone support pillar in the center. It is filled with water a foot deep. Another tunnel continues 100 feet further and opens into a larger chamber. On the right side of the chamber is a smaller, cross-latticed grate about 2 feet across. The passage from this grate appears to continue about 150 feet before reaching another grate.



Large chamber system
This chamber also square shaped, with a curved opening coming from the tunnel. There are three grates similar to the entrance grate on the three sides of the chamber other than the entrance. The room is supported by two stone pillars, and there are two platforms ten feet in the air on the left, and on the far end of the chamber. In the center of the room are two stone support pillars. There are two platforms raised up about 10 feet above the floor, each with railings, and two pathways that meet a few feet in and continue forward.

The tunnel reached by the pathways opens up into another small chamber that has tables, chairs, and weapons. There are archways leading between the chambers, with gated portcullis doorways that can be lowered with the press of a button. There is a sketch on the wall of one chamber with the tunnel layout, and a spiral staircase that leads to the entrance within the city of Nicodranas.

City entrance
This entrance is located in a small office, with a desk, a stool, odd stacks of paper, and partially melted candles. In the back is a trap door leading into the Sluice Weave.

History
The Mighty Nein entered the Sluice Weave while trying to find Algar Dyomin, an employee at the Sluice Weave and a patron of the Ruby of the Sea who had been bothering her. They successfully located one of the entrances in the harbor and after having Frumpkin scout ahead, broke in.

Inside, the party encountered several smaller water elementals, which they were able to fight off, before reaching the larger chamber. There, Algar commanded Xundi, a marid whom he controlled via bracelets, to attack the party. The Mighty Nein tried to avoid hitting Xundi, instead focusing on Algar and more elementals, though Xundi attacked them while under Algar's control. After Fjord cut off Algar's hand with the bracelet, Xundi was freed from Algar's control and asked to kill Algar. When they told him they wanted to question him, he offered the party a favor should they ever come to his palace. The party then interrogated Algar, who eventually led them out of the chambers into the office within the city.
