"Firs' years, this way!"

Never thought you'd hear that again, did you? This time, though, the familiar call seems to be nothing more than an echo, as there is no groundskeeper to keep watch over the little boats tied to Hogwarts' dock. Perhaps the Hogwarts staff feels that their newest graduates are more than capable of sending themselves off, even if the lake still has chunks of ice floating on it?

The same fleet of magical boats that carried you to the school as a firstie still bob gently on the dark, deep, and frigid lake, waiting for your departure. Two graduates per boat, please, and be careful not to tip over. The boat will take off once you release its rope from the dock.

Enjoy your last trip across the Black Lake, and be mindful of Barty.
