Swamped

"Sir, with all due respect, we've just escaped combat. It's very important that I pass along what I know about damage to the ship and crew..."

"It is," the Captain agrees. "But this is even more important than that. We have not entirely escaped."

He's getting that knowledge from Nual. Which means you're not expecting to have it clarified. Still, worth a shot.

"Then who's attacking us? Cultists we haven't found? More sea creatures? A wizard? The forces of another god? Merfolk?"

Instead of answering, he walks over to the porthole. You follow him, and look out.

And you can see it in the distance. The Ship of the Dead.

It's unmistakable, even this far out. No other ship could move so fast with its sails torn and enormous holes in its hull.

"The sun has just begun to set," the Captain continues. "We have until nightfall before they attack in full force. We need to make the most of that time."

Easier said than done. What can you even do to prepare?
