Crashed End Ships/ Ender engine (flotater)

In the overworld, End ships can be found buried in mountains, ruined but intact. It holds treasure inside, though the elytra is long gone. Inside this ship, you can find the Engine block, a new block that works exactly as the Flotater from the poison potato update. This would be a way to get a new block while making the world feel more immersive. It also serves as a tribute to the 1980 D&D adventure, "Expedition to the barrier peaks"
