Where the River Zeitlupe flows into the Wildwasser River, the large, triangular area of land to the north-east is so waterlogged that an area of marshland has formed over the millennia that the two rivers have been flowing into one another. The people of the Barony of Hohensten, have been unable to reclaim the land of the Sumpf for building an agriculture, though they have tried many times to drain the marshland. However, the low elevation of the area makes draining the area an incredibly hard task, especially given the limited resources and engineering knowledge of Hohensten’s inhabitants. In addition, the Sumpf is rumoured to be a refuge for all sorts of malign creatures, who would prey on those who would stray too near. It is also known that a Hag, known simply as Hulda, has been resident in the Sumpf for many generations. Hohenites, including members of the baronial house, who have summoned up enough courage to seek her out, have gone to consult her, and buy magical favours or curses from her.
