These are the "Alice" versions of the Egyptian tomb style, I see (Looking Glass) 😵😉

And maybe the player's version shouldn't have the full key listing?

Sorry to say I missed this live today, as my ISP decided it wanted the afternoon off, so arranged "a major outage in my area", that seems to have lasted most of the afternoon and early evening. Took me nearly 40 minutes to get through to them on the phone ("You can find the answer to most questions more quickly by using our website"...), despite the fact my call was apparently important to them, as the nice lady bellowing in my ear kept insisting. Which had of course already given me the clue that it wasn't just me that was having the problem...

Joys of technology, eh?

There's a Darklands City now? Didn't see that coming - but only 'cos y'know, dark...😎🌑🔭

You could also have masts below the decks, from the base of the craft, though that depends if it needs to land or not, or horizontally out from the sides. There is a probable balance issue with masts only on the top - wind in the sails there will tend to tip the craft over end to end. Sailing ships rely on heavy friction with the sea, and their ballast plus keels to stay upright, but in the air, none of this is an option. Looks nice though, I know!

Magical engines would be more likely than combustion engines, I'd have thought. Combustion engines are just so incredibly inefficient, it's hard to believe those with access to magic wouldn't come up with something far better and more elegant.

As for propellers, the basic real-world concept derives from the Archimedes screw, c.200 BCE, so some bright Strompheian folks could have developed something similar for aerial use already, perhaps.

As with other things taken as "universal beliefs" by many (especially elsewhere on the Internet...), the spiral-staircase thing seems to have been a purely late Victorian/Edwardian speculative invention; see this usefully-referenced blog posting, for example.
