Arthindol

The Terraseer was originally a powerful ancient sarrukh lord who eventually became a lich and thereby survived the downfall of the ancient progenitor race. He dwelt, ever since, in the ruins of ancient Oreme, rarely interacting with the outside world. Most notably he served as a source of ancient arcane knowledge for the Netherese Empire.

Arthindol built the watchtower at Old Owl Well, as can be asked of Agatha.


 * : The Terraseer appeared before Karsus and stated "Mystryl was about to face her greatest challenge - one that could alter the perception of magic for all time."
