Okay, I kinda had an idea for a new antagonist. What if there was a rogue Quarian group that decided that instead of trying to fight the Geth, they would try to regain control of them by becoming superior to them. They would be a small group, sort of synthetic/quarian hybrids. These rogues would control a large army of Geth-like synthetics, and are waging a war in the Terminous Systems.

However, they also want to replace all organic life in the galaxy, believing that synthetic machines are the only ones who are capable of peacefully ruling the galaxy.

Geth at the moment are not much of a threat to the galaxy, seeing as anit-synthetic warefare has been improved.

Okay then. I'm just trying to think of something differant, Most of the conflict I've seen in your RPs are all about Terra Firma right now.

That was before the reset, currently the Geth and Batarians are the main enemies. Currently Terra Firma is a political party instead of a rebel group now. Geth are only threats in large groups.

Ah...
Okay. Sorry, that must be a new guy thing.

I will keep refining my idea here then, and maybe it can be used later.
