Granted, but I just saw the Phantom (full name is Phantom Terrorist [the enemy of almost all ID]) ID as the closest to being an enemy to all, without being an NPC faction like Xenos. Just use their tag, and Phantom Terrorist ID until/unless Nomad ID is unlocked.
Also, I was thinking the infested ships using normal IDs, as other factions can read it. I want it to have to be found out its infested (basically by Bs| the Order faction and dealt with by them) and keep the houses close to war that way as they cannot prove the fact that I'm infested unless they can get aboard the ship.
