Aliens have invaded Earth...
And I'm pretty sure it's my fault.
I needed power to protect myself and those I care about. So I took it. But all power comes with a price, and this one will be paid by innocents.
To save the people I care about (and everyone else who happens to live on either world), I must fulfill an ancient prophecy.
Step one: Escape back to Earth.
Step two: Find a greater god that has been missing for millennia.
Step three: Convince it to help... Somehow.
No problem, right?
