Sinjin

Sinjin is a raider leader in the Commonwealth in 2287.

Background
The Sole Survivor has to confront him as part of the quest The Silver Shroud as a final boss. After the Sole Survivor decides to help Kent Connolly in his mission to bring law in the streets of Goodneighbor and kills some minor agents of his, Sinjin uses Northy and Smiling Kate to do his dirty work.

Unfortunately for him, the Sole Survivor kills both of them and is able to retrieve clues about him. Vengeful, he personally captures Kent in Goodneighbor and takes him to his hideout, the Milton General hospital. He holds him captive until he is killed by the Sole Survivor.

Appearances
Sinjin appears only in Fallout 4.
