Scarlet Marpenoth

Scarlet Marpenoth The Scarlet Marpenoth was a submarine secretly owned by Jarlaxle Baenre.

Description
The submarine had a top speed of 2 mph (3.2 km/h) and required a minimum crew of two in order to be properly piloted and kept. Its interior was always kept dark, so that its crew had to rely on darkvision.

The ship's air supply circulated between all its chambers through a complex ventilation system powered by quasi-magical machinery. Its airtight doors were kept always locked.

The Scarlet Marpenoth's engine was a quasi-magical device that controlled the ship's depth, as well as the steering fins and rudder, and powered its propulsion system. It could be piloted from the ship's control room.

The ship had a defense system that allowed its outer hull to become electrified for a short period of time.

History
The ship was designed and built in the island-nation of Lantan. About one year before the arrival of the Sea Maidens Faire in Waterdeep sometime in the late 15 century DR, the submarine was acquired by Jarlaxle and was kept secret even to the crews of the Faire's sailing ships.
