Big Fish (Part 1)

Saleen's diving combat vessel was only 18 meters long. It had a long and narrow body, which was divided into four parts: holds for rest, storage room, control room and an alchemy room installed specifically for mages.

The material used for building the ship was special, as it was made of refined thundercloud wood. The backbone of the ship was made of bones of ancient magic beasts that Saleen had gifted to Jason. 

No metal was used. The advantage was that it made the vessel extremely light, which meant that it could travel at very high speeds.

The ship was named after Saleen. The final part that Saleen installed on the ship was a Hogina's Gun that he had crafted. While the Thunder Dragon Blaster was incredibly powerful, its materials were incredibly rare. 

Even if Saleen slaughtered all 24 thunder dragons he had with him, it still would not be enough to craft the one that he had with him.
