Extremely dense, striated, lignous material obtained from the trunk of the howood tree, a rare plant native to Pretoria (0406 Deneb) and known to grow on Pysadi (3008 Spinward Marches) and Violante (2708 Spinward Marches).  The trees concentrate metals from the soil in their extremely tough bark.  Howood is aromatic and its scent is especially pleasing to vargr.  It is also beautiful; the size, colors, and intensities of its rings and striations vary unpredictably with the characteristics of the environment in which the plant grows.
