Devil tree

"A tree with a taste for human flesh, a tree like those which had long ago smothered the Valley of Gold."

- Rowan of the Bukshah

The devil tree, or Unrin tree, is the name given by Zeel to the living, flesh-eating trees which grow on the Mountain and in the Pit of Unrin. The devil tree is able to move on their roots, and its branches can move and grip prey. The trees have also been referred to as Unrin trees. It quickly spread throughout Rin, but was destroyed by Slip-Knots.

Early history
The trees overtook the Valley of Gold due to the residents removing Slip-Knots.

Anatomy
The devil tree is a squat and twisted species of trees, with stubby branches, tipped with clumps of dull purple leaves, and fat white roots.

In its young form the tree is a small bush with tiny branches and glossy leaves. It has small red flowers growing along its branches, and is covered in little red berries.
