The origins of Covenant are tied closely to Roslyn Chambers and the Broken Mask incident in 2229. After losing her parents to the rogue synth infiltrator sent to Diamond City, Chambers became determined to create a way to identify synths among the general population. For decades, she labored to create a reliable test and nearly sixty years later, she believes she is close to creating one. The Covenant settlement is the culmination of her research, a prosperous community that is designed to attract dozens of visitors each week, so that Chambers can have a large enough sample to determine the efficacy of the SAFE test. As the Covenant is staffed by survivors of Institute attacks sworn to secrecy and believing in Chambers' vision, the project seems destined for success.
Every visitor to Covenant is given a psychological evaluation - the SAFE test - before being admitted into the shelter. Trouble is, the SAFE test is actually a barely modified Generalized Occupational Aptitude Test, and this travesty of psychological testing is used to identify potential synths. People suspected of being one are abducted to the compound, where they are forced to answer the questions in a controlled setting and tortured if they refuse. The torture continues if they try to avoid answering the questions, all in an effort to perfect the detection method. Failures are actually encouraged as necessary sacrifices. All interrogations inevitably end up on the dissection table, where Chambers verifies whether their victim was synth or not by opening the brain. What is even more ironic is the fact that the Institute is fully aware of the Covenant's true purpose, and do not even considering it enough of a threat to intervene in any way.
