Rocket-propelled Pokemon Tabletop

Lucian turns to let the captain pass (and also see what that racket is - seems like some wild corphish, probably to be eaten later; with all the deep sea 'mon about, the seafood industry's probably a big source of Aroan revenue, so that's not too surprising), then surreptitiously scoots back into the cabin to avoid getting involved - and try to figure what the noise was.

He's read the manual not unfamiliar with smoke-filled boats (though those were admittedly yachts), and figures he can figure this out. Breathing through his collar, he scans for blinking lights (if there's an audio cue there's almost certainly a visual one to go along with it) - or a sonarscope, come to think; with all the deep sea 'mon about (as alleged by Gerald), Aroan boats (especially fishing boats) would likely have early-warning systems to steer clear of high-danger aqualife. (That said - is the beep persistent? How often does it go off? Pitch? Length? These things are important to take note of.)

He's careful not to touch anything, though. Captains (and important or leaderly people in general) usually get pissed at mere unsupervised loitering in their cabins (offices, w/e); Arc help you if you manage to mess up their workspace.
