Ocean Headquarters is a set in the custom theme Dragons 2013 by Sir_REX. It has 308+ pieces and four minifigures. Like other sets in the theme, it includes a wall piece. This is one of Sir_REX's favorite sets he made for the Dragons 2013 custom theme, and as such, would be classified as a "Limited Edition Set."
The Ocean Headquarters of the Dragon Hunters is an abandoned shipping dock, connected to the coast by a small bridge of sand. As such, the bottom layer contains several barrels, boxes, and crates. The top building is home to a type of control or command center; the second floor can be removed. The Water Dragon can be a steed for two Shadow Riders, although only one is included with the set.
