Former crystalline monster that inhabitated kal'tsits spine to a independent person in her own right.

an ancient, artificial, biomechanical entity connected to the civilization that existed on Terra before the modern races. For thousands of years, she and Kal'tsit shared an extraordinary symbiotic existence. She was Kal'tsit's weapon, companion, protector, and an extension of her very being. But she was also an individual whose identity, memories, and future would eventually become separate from Kal'tsit's.

One of the most important turning points in Mon3tr's history occurs after Kal'tsit disappears from her life.

Following the severance of their connection and the events involving Priestess, Mon3tr retreats into her crystalline form. She subsequently develops a humanoid body, gradually becoming the young woman introduced as the modern Mon3tr operators know of today.
