Vundwood

The vundwood was a species of tree that grew throughout Faerûn, particularly abundant in the hills of the Western Heartlands and the Tunlands of Cormyr.

Description
These scrubby trees were relatively short, rarely growing over tall. They were comprised of many small outwardly growing branches. Their wood was reddish-brown in color and smelled somewhat of cinnamon. They were covered in thin, dark-red bark and had pale-green leaves that were bordered with white. These leaves turned to yellow when winter was approaching or as the tree neared death.

Uses
These trees were often used as firewood or felled and dragged into tangled arrangements to form pens for livestock.

When vundwood was used in the creation of magical items it imbued them with a sort of arcane echo, whereby they gained extra changes every few months if they were not entirely depleted.

In addition, vundwood served as a universal replacement material component for both arcane and divine spells related to the recalling of expended spells or the augmentation of a spellcaster's magical capacity.
