Treatise on the Nature of Matter (artifact)
A rare collection of the surviving works of Khaci'aex, an enigmatic fourth century BI Aspomnox philosopher, mathematician and Magi. Originally from Vysbael, his unorthodox school of thought preached a controversial dogma that eventually saw his flight to nearby Aspomnox, whose liberal rulers were more content with allowing him to teach his doctrine in peace. Today, he is mostly remembered for his role in founding the earliest known academy that exclusively studied what would become Dead Magic, and Aspomnox would continue to hold the distinction of being the only major proto-Aversarian city state to primarily utilize it rather than Living Magic for the rest of its independent history.
