The Boathouse is a decaying riverside structure whose broken dock and damaged shelter still show how the site once served passing boats. Weathered timber, missing sections and neglected storage create an uneven interior, while the waterline remains only a few steps from every part of the building. The map feels abandoned without becoming visually empty.

For Age of Ashes: Tomorrow Must Burn, the ruined boathouse works as a small exploration or ambush site along an old water route. A GM can use the dock as an exposed approach, the remaining walls for cover and the shoreline as an escape route that demands a boat or a swim. Outside the campaign, it functions as a forgotten ferry stop, smuggler landing or collapsed lakeside storehouse where the water is as important to movement as the building itself.
