Well, that's interesting, without an exclamation point, Item #2 Apparently the other Duergar ship is only 60 seconds out from the beach. Cast haste on a character then immediately set sale. They intercept you, and engage in conversation. If you immediately start a fight, you become lethargic and stunned. 10 rounds of haste at 6 seconds a round, then you are lethargic. This implies they were right out there, and should have been easily in sight before you left the dock, as you are not moving fast at all.
