Forum:KB:Empress Teta's age

A friend and I are working on a project that is set in the years after the Great Hyperspace War (roughly 300 years afterwards). We'd like to set part of it in the Empress Teta system, and involve Teta's descendants. However, the wiki article on Empress Teta is vague as to how old she actually was, or how long her reign lasted -- a paragraph at the beginning says her reign lasted 175 years, while a later part of the article says she lived 175 years. Seeing as she was apparently an adult when her reign began, they can't both be right.

Do we have any idea as to how old Empress Teta was when she died, or, barring that, any info on how old she was during the Great Hyperspace War?
