Swamped

You don't get a lot of ideas.

But the main one that comes to mind is that it doesn't seem likely to be a coincidence that you've got a flotation spell and a spell - or something - pulling the ship down. For one thing, you can't see how it would particularly benefit anyone to make the ship float.

So starting from there. The flotation spell comes from a symbol. A symbol that somebody was in a rush to make, judging by the knife left in the floor. Now, that would make perfect sense if they knew something was going to pull the ship down... but how would they know that? You didn't feel anything until the floating started, and the wizard just explained how hard it is to detect the spell in the first place.

The easy answer to that is, someone planned to pull the ship down, and whoever made the symbol knows about the plan. Either they overheard something about it, or they were in on it and changed their mind at the last minute.

So, your next question is who did it. Was it the bug golem? Or was that thing trying to stop the effect? You've got no idea.

But the other most likely suspect would be whoever stays in this room. And there's an officer here who might know that.

"Mr. Resk," you ask. "Whose room is this, exactly?"
