Tai Xuan Gang Wood

A unique spiritual wood native only to the Minor Spirit Heaven (Xiao Ling Tian). It grows extremely slowly (half an inch per century, one leaf per millennium, one flower per ten thousand years). It is an extremely rare and precious material for refining treasures and magical instruments, highly coveted and a cause for conflict within Xiao Ling Tian. It is said to have mutated from several spiritual woods under specific circumstances and does not exist elsewhere.
