Three Dog

Three Dog is the radio host of the Galaxy News Radio station in the Capital Wasteland in 2277, playing music that likely would have been heard on the radio in the years leading up to WWII as well as the post-war era, and doubling as a news anchor.

Background
Born to parents who made their way in the world as members of a traveling theater group, Three Dog grew up listening to rock music, hating the government that he never knew (but surely caused the nuclear holocaust), and fully believing in the rights of free speech and communal law. At some point before he established GNR, he was taking Jet and stumbled across Oasis.

He established GNR in 2272, together with Margaret, a radio technician. Should Three Dog die for any reason, she will replace him as the radio host. Since he began, he's been broadcasting to the Wasteland with his voice, public service announcements, and music. At times he makes jests at Enclave Radio.

He's obsessed with the "Good Fight," interpreted by him as fighting the government and other endeavors he considers noble. Often, this means he supports what the Brotherhood of Steel does.

Daily schedule
He stays in the GNR building throughout the entire game and does nothing but offer aid for the Following in His Footsteps quest and giving you an unnamed side quest that can give you a few items that are level-dependent.
