This is the Black Ship from Breath of Fire III, a JRPG that I've loved since I was a kid. It's a very nostalgic game for me, so I had to make a tribute to it somehow. I always used to draw this ship too, so I figured why not make it in Minecraft? After all, it fit well in the high-tech city I ended up putting it in.
In the actual game ,the Black Ship is automated and carries machines from the deserted, barren old continent to the new, lush continent, across a stormy and violent ocean that most other ships couldn't cross.
