The Pygmalion Plot

For over 200 years, humanity has trusted our Ssenn allies. But that trust is thrown into question with a new discovery on the world where humans first learned to live with that advanced race. Soon after, the Commonwealth is summoned to a distant world to meet with an unknown race while at home, dissent is growing under the Regent's long reign.
Can the Commonwealth hold together, or will internal divisions and outside forces drive us apart?
