Enemy (Minor or Major)
Someone out there hates the character and wants him dead.
The value of the Hindrance depends on how powerful the
enemy is and how often he might show up. A Minor Enemy
might be a lone gunslinger out for vengeance. A Major Enemy
might be a supernatural gunslinger who wants your hero dead.
If the enemy is one day defeated, the GM should gradually
work in a replacement, or the hero may buy off the Hindrance
by sacrificing an Advance.
