Metzger started out in chemical engineering, designing various safety systems and eventually starting a company that manufactured safety systems for chemical plants. In the year 2072 she inherited several billion dollars and managed to acquire a weapons manufacturing company under the newly formed Metzger Investments LLC, which, due to a war in 2075 and clever investments on her part, managed to make her one of the most singularly wealthy individuals in the world. Eventually the company expanded into semiconductor fabrication, nuclear reactor construction, and steel production. Growing to be a vast industrial company.

Later, due to bad press related to the Elk Grove incident where several hundred tons of highly volatile chlorine trifluoride for microchip production detonated, Metzger Investments was renamed to Theseus Technologies LLC.

Theseus Technologies LLC. managed to ultimately acquire considerable wealth and, due to a mixture of some innovative financial instruments and bribery, the entire planet of Polypheme. The icy world then became the heart of Theseus, each inch of its hydrocarbon seas and methane snow touched by industry and by change. Its cold providing the ability to run many industrial processes more efficiently than on other planets.

Wealthy, ambitious, sadistic, and lacking in significant restrictions she has managed to become infamous for her taste for human suffering in some circles.
