Within a few hours of leaving Rickety's, they'll spy a large warship of Sargravan design, heading towards the dock, flying the flag of the Shackles. Likely a recent capture, and possibly with only a prize crew... but it's also possible the original owner's ship might not be too far off, either. It wouldn't be hard to avoid the ship, but it might make an easier first fight with the new crew, although it could also prove to be incredibly difficult, given how large the ship is, compared to theirs.
