The Kraken's Keepsake
Elemental galleons use a bound elemental to propel or draw them through the water at great speeds.
The Kraken’s Keepsake is a House Lyrandar galleon that travels between Sharn and Stormreach on a regular basis, carrying passengers and cargo.
On one such trip the ship was damaged by a saboteur and had to beach on the Island of the Writhing Horde. Serpentfolk attempted to kidnap the crew and passengers, but were foiled by a number of adventurers who were travelling on the ship.
