It is a friendly village which hides a secret - you will unravel it by accepting the only quest available here, Human Error. In order to gain access to the settlement, you must complete the test that will determine whether you are a human (and what sort of human).
You will find Patricia the medic and a merchant Penny in the settlement.
If you haven't saved Amelia during the quest, the Covenant can become a settlement,
However, if you did save Amelia and the village is unfriendly towards you, it can become your settlement only after completely eliminating people and turrets. It is worth mentioning that the location is one of the best for building a settlement (nice neighborhood, complete buildings, high security level).
