More like RL ship combat. They have canons & muskets, not browning 50s.
I'm guessing that anyone with airships is going to have decent ranges on their weaponry. Especially given that what we've seen of their weaponry isn't exactly primitive. Rifled barrels aren't
that important to range.
The elf ship won't be on the same side, they'd be near-tangent. Therein lies the danger. You take shots at a guy peeking out of cover with a musket, at range, and you expect the cover to come out of it unscathed?
The problem here is that I don't agree with your assumption.
The fact that they're all here is rather convenient, and the elven ship shooting at our house and sending a party to board it is also strange. They must have had some interest in the node, because discovering us was a discovery. They weren't here for us.
That doesn't mean they'd care. For all we know, the elves were interested in seeing if this node was worth mining and the dwarves just wanted to kill the elves.
They aren't too plussed by us being a dragon- we've heard of a dragon-king, and the reactions indicate we're not too common. Their technology may have made them cocky, and steampunk's instilled in me a tendency to assume everyone's nationalistic. Aka not estimating opponent's capabilities fairly.
"Sir, it looks like there's a...dragon on the rock."
"Destroy it too, the vermin's probably in-league with the elves."
That kind of thing.
We're clearly not a normal dragon, however. In any case, it would take quite a stupid dwarf to decide to antagonize a dragon for no real reason.
Do we really want to stay and have our hand forced like that?
As opposed to what, flying away and forcing our hand in a different direction, more strongly and certainly?
Anyways:
Climb over to his side of the rick and greet him.
