Starwood

The starwood tree is anathema to all things unclean; no truer weapon can there be against corruption than arrows fashioned from its boughs. 1a Such arrows glow with an unnatural light and emit a piercing wail when they draw blood, chilling the soul of even the bravest warrior. 2a

High Elves have been known to craft staves and Dragonships from starwood, the wood bled resin glitters like shimmering gold, making the whole hull resemble the scales of a dragon. Such wood flourished in the forest of Anhara Draconis, but was burnt to the ground by Dark Elves during the Sundering.
