Rowan Tree

The Rowan Tree is a tree found on the Isle of the blessed. This tree is very important to the High Priestesses and all the followers of the Old Religion.

In the audio-commentary of The Coming of Arthur: Part Two, it was revealed that Morgana and Morgause's crest when they conquered Camelot, the red tree on a black banner, represents the Rowan Tree.

During the Great Battle for Camelot, Morgause gave Morgana a staff carved from the wood of the Rowan Tree to allow her half-sister to resurrect four skeletons using necromancy. Later Merlin destroyed the staff causing the skeletons to collapse (The Tears of Uther Pendragon).

It is possible that the Rowan Tree will appear in Series 4, for Morgana and Morgause will travel to the Isle of the blessed.
