The Whitewood is the Shadowfell analogue of the city called Qualinost on the Material Plane. Largely subterranean, the Whitewood is built into the hollowed-out roots of ancient birch trees. Its lightless and silent tunnels are lined with the trees’ papery bark. The city’s resident shadar-kai navigate the tunnels with magical light sources that produce no flame, and pass without trace through the dead birches’ innards.
Seth Mase has twice visited the Whitewood in his dreams, in distinct iterations of the defense of Qualinost, and each time he has spoken with a young shadar-kai named Nalani who dwells there. It is unclear who governs the Whitewood, or indeed whether anyone but Nalani lives there at all.
