Steles are the tools used by Shadowhunters to draw runes onto their skin, weapons, and other materials. They are made of adamas and crafted by the Iron Sisters.
The concept of the stele was developed in the late 19th century by French botanists P. E. L. van Tieghem and H. Doultion as a model for understanding the relationship between the shoot and root, and for discussing the evolution of vascular plant morphology.rom Wikipedia, the free encyclopedia. In a vascular plant, the stele is the central part of the root or stem containing the tissues derived from the procambium. These include vascular tissue, in some cases ground tissue (pith) and a pericycle, which, if present, defines the outermost boundary of the stele.
