The Ent Stones are petrified trees located behind the walls of Nelrenael. They hold records of druidic history pertaining to the Nature Protectorates and the observations of Aredhel spanning the period from when she became a Hierophant to just before ascending to godhood. The writings cover 23 petrified trees, each with a history of its own. Each of these trees was once a treant that fell to darkness, with some transforming into dark treants, undead treants, or other malevolent forms. When tracked down, they were petrified, broken into pieces, and transported back to Nelrenael to be reassembled. Aredhel then utilized the latent energies still present in the petrified treants to bind the magical writings.
No comprehensive volume of information has been produced from an Ent Stone, as the druids steadfastly endeavor to maintain the secrecy of their activities. They have even embarked on missions to penalize those who have managed to reach the Ent Stone and absconded with reproduced writings.
