Yes, they have engines. I also had the idea of airships being built around floating islands at their core that provide levitation while the engines give thrust, but idk if I should implement that idea or not. On the one hand, it seems like the logical thing to do when there are floating islands everywhere, but on the other it's kind of... Mundane? Like it's not some high tech anti-gravity thing, it's just slapping some big engines onto a piece of floating rock and dressing it up as a flying ship. Feels like I can do better than that, idk. What do you guys think?
