A clear, cold lake in the northeastern interior, Hakö is Roule's largest freshwater body and the source of the Hanli River. Fishing villages dot its shores, and wealthy halflings maintain summer estates on the southern bank where the views are best. The lake is deep—deeper than anyone has successfully measured—and local folklore holds that something lives at the bottom.
The previous inhabitants considered Hakö sacred. Roulean developers have found carved stones on the lakebed during construction projects, which are quietly disposed of. A ruined temple complex on the eastern shore has been converted into a fashionable resort, its original purpose carefully unmentioned.
