The Spectrewood.

The Spectrewood is a huge forest that dominates much of the northernmost reaches of the Tian Xia kingdom of Shenmen.1 Before the fall of Imperial Lung Wa, the Spectrewood was one of the most valuable assets of Shenmen: the officials of Lung Wa cared little for what happened within Shenmen just as long as the lumber from the Spectrewood continued to flow.2
