The power armor that they dawn seems to be stolen from the Enclave. When they speak it is very muffled as the speaker on the helmet is broken. They alternate between two weapons, a gatling lazer and a barbed/bladed minigun. The gatling lazer is attached to their back.
In 2089, the wanderer first appeared in the glowing sea. This mysterious power armor wearing figure barley speaks,only walks around killing off all the glowing creatures. They are but a myth to the commonwealth, as nobody has the will to walk into the glowing sea. Nobody knows why, or what the Wanderer wants.
