Renewal

The Renewal is a cult in Fallout 2.

Background
The Renewal was founded by a mole rat who became sapient after an FEV dose. This rat settled in Gecko, named itself "The Brain" and began seeking to take over the world. Its members wear talismans of ankh.

Brain sought to build an alliance between Gecko and Vault City based on power from Gecko being sent to Vault City in exchange for medical research on how to "restore" the ghouls to humanity. Brain was recruiting followers from ghouls and glowing ones living in Gecko, but could not talk to somebody in Vault City because of xenophobia.

The Chosen One can become a Renewal member and work towards completion of Brain's ideas. This includes fixing the reactor, optimizing it, and convincing McClure to accept an alliance between the two locations. However, a bug prevents the play of an ending slide that reflects these choices.
