Zalantar

Zalantar, also called the blackwood, was a subtropical tree that was usually found in Chult or other southern areas.

Description
Zalantars grew oddly in the sense that one plant was composed of several tree trunks that stemmed from a central root system. Their leaves were usually white or another light color.

The pure black wood from a zalantar tree was called darkwood, or blackwood in the North. The wood was as hard as normal wood but much lighter. It was coveted as a building material because it was durable without being too hard.

Uses
Items made from zalantar weighed half as much as normal wooden items of the same type. Darkwood weapons and shields were thus very light and made to high quality but also more costly.
