Create a moonbase (CYOAH! Redux)

Previous: Ally with the Pact of Stars

You have clearly chosen to establish a moonbase and the base is currently under construction. The Firstborn and the rest of the Pact are helping you establish the base. You have the base completed 2 weeks later. It's been nearly a month since you arrived at Sol and the Invasion force is ready now. Earth is ready for an attack, but multiple potential enemies are in the system. You have 3 choices:

a. Clear the system of enemies

b. Invade Earth with everything you have

c. Send a small scouting party to Earth and establish a small outpost there to prepaer for the full invasion.
