The Barkmilk Vine is a robust climbing plant native to the humid canopy zones of Saethera. It produces a thick white sap used for sealing wounds, binding fibers, and waterproofing materials. The vine overgrows branches to form dense latticeworks that support small canopy fauna and stabilize upper-forest structures. Its fibrous stems are durable, flexible, and widely used for field repairs and temporary shelter construction in high-humidity regions. It is able to grow upon living fauna.
