Tangletree

Tangle-trees (or tangletrees) are a common occurence in the Free Kingdoms. They are famous for growing many sturdy lengths of fiber, useful for creating thick cloth and rough clothing.

Story Information
Tangletree fiber is extremely tough, at the cost of any form of comfort. This means that it can be used to make rope, tapestries, dragon saddles, and other durable materials, often in place of leather (which is scarce anyway cause that means fields). Tangletree, however, is not often used on clothing or anything that would touch skin. To do so is a sign of tremendous poverty. Jeriel probably starts the series off in some tangletree tunics, then ditches them when he becomes a rebel leader. That's a plot point.

It can be dyed in many colors, and retains its hue fairly well. This means that things are often passed down from father to son, allowing rich families to save money, and have heirloom saddles and the like. If Jeriel ever fights some prissy Free Knight boy, the kid would brag about it.
