Undead Skeletons

The Undead Skeletons were created as an army during the Battle for Camelot.

Biography
Using the rowan staff, carved from the rowan tree on the Isle of the Blessed given to her by Morgause, Morgana was able to bring life the dead of Camelot and use them to fight the Knights of Camelot as they fought the armies of Cenred in the Great Battle for Camelot. Although she wasn't an experienced witch, the Staff's power guided her. The undead army were all skeletons and could be reduced to piles of bones. But even in such state they would continue to fight. After Merlin destroyed the staff, the undead army was reduced to dust (The Tears of Uther Pendragon). However, Morgana was the one who took credit for managing to defeat them.
