Mark of Caesar

The Mark of Caesar is a quest item $$

Location
It is a necklace given to the player character by Vulpes Inculta (or Alerio if Vulpes was killed) upon exiting The Tops casino after completing Ring-a-Ding-Ding! as part of the quest Render Unto Caesar. The Mark allows safe passage to Caesar's camp, even if the player has a low reputation with Caesar's Legion.

Bugs

 * You can get a second mark when leaving The Fort.
 * It is possible for the player's reputation to decline after receiving the Mark. For example, if the Courier had an Idolized reputation with the NCR, it could become Wild Child after receiving the Mark. Members of the NCR may also be hostile towards the Courier for seemingly no reason, even while wearing NCR faction armor, once the Courier receives the Mark.
