Thomas Moore

Thomas Moore is the anti-slavery denzien of Vault City. He has ties to the Bishop family in New Reno, but is in fact only hired by NCR for doing propaganda benefitting them, although indirectly not visible, it is evident that NCR is a "ranger"-state and anti-slaver, so it is kind of promoting their views.

Behind the scenes
He is often believed to be a throwback to either Sir Thomas More or Michael Moore, but in fact he's just a reference to Chad Moore, one of the Fallout 2 developers.

Appearances in games
Thomas Moore appears only in Fallout 2.
