Saga of Jaraah
In the center of the Kingdom of Kermaan is a large forest of Ice Trees. These extremely slow growing plants are entirely black (wood, bark, and foliage). The forest has avoided the ravenous logging that has been the fate of most forests because the wood burns very slowly, gives off very little heat, and produces foul inky smoke when burned. It is also nearly impossible to work without shattering it. This utter lack of utility combined with the determined efforts of a small band of druids and ranger allies have kept this forest largely intact.
