Quaere Verum (Latin: Seek the truth) was an organization instituted and destroyed before the Great War.
Quaere Verum was a small pre-War organization dedicated to exposing the truth about aliens.  [verification needed] Quaere Verum was swiftly eradicated by the federal government not long after the MPLX Novasurge prototype plasma pistol was stolen from them by the group. 
It was generally considered to be a crackpot group for their belief in the existence of an alien conspiracy.

It is said that Alien technology was the basis of many of the Enclave’s more exotic and impressive weaponry and robotics, and even toy manufacturers such as Wilson Automatoys weren’t immune to these accusations. Recently, after the discovery of an Alien body in Fort Bannister, the shocking truth was revealed. The Aliens are not only real and alive, but they’re back. And they’re pissed."
