Set

Set is the leader of all the ghouls in Necropolis in 2161, except for the underground ghouls who lived in the sewers and the glowing ones who live in Vault 12. He has a son called Typhon.

Background
Set styles himself as leader of Necropolis, but in fact he's a figurehead put in place by the Master to keep the ghouls in line. Set hates the Master, but fears him more. As a result, he is frustrated and short-tempered, with a nasty tendency to lash out suddenly against any who cross him. His speech is abrupt, harsh, and so jargon-laden he is, at times, a bit difficult to understand.

Set is a rude ghoul, with one hell of a mean streak, whose colorful vocabulary consists of the extensive use of the word "dirtnap" and the phrase "standing in my shadow". According to his son, he had a bad temper before the war and ghoulification has done nothing but worsen his attitude.

In spite of Set's hostile attitude, his approach to running Necropolis appears to be one of relative non-violence, commanding his ghouls to attack only those who approach the city at night or who pose a significant threat, even allowing the underground ghouls to live peacefully in spite of being aware of their hidden location. Outsiders are permitted into Necropolis during the day, and Set himself, while volatile, aggressive, and not against harming those who anger him, tends toward honesty and favors those who express a desire to aid him and his ghoul brethren. He is quite annoyed by the super mutants. It is possible to find a note from the Lieutenant to Set, ordering him "to watch for pure-strain humans": this shows how much he disliked them by not capturing the Vault Dweller.

He is not mentioned in the Vault Dweller's memoirs, but the Vault Dweller did kill the super mutants, which led to the slaughter of everyone in Necropolis, including Set himself. The Cafe of Broken Dreams features Set among other Fallout characters: Set's dialogue there suggests that his verbal repertoire may be the result of insanity such as him discussing his phrase Dirtnap and how he likes to say it.

Quests

 * Destroy the Super Mutants at the Watershed: If you manage not to anger him, Set will ask you to get rid of the super mutants by Necropolis' watershed.
 * Fix the Necropolis water pump: Now that the super mutants are gone, Set wants you to repair the water pump.

Other interactions
Set is annoyed at the super mutant presence in Necropolis and attempts to recruit the Vault Dweller to take care of the problem. He will also insist that the player fix the Necropolis water pump if met after already recovering the water chip. He may also try to take advantage of low intelligence characters such as intelligence level 1.

Appearances
Set appears in Fallout. He also appears in Fallout 2 in the Cafe of Broken Dreams special encounter. You can also find his son, Typhon, in Broken Hills in Fallout 2.

Behind the scenes

 * In Ancient Egyptian mythology, Set (also spelled Seth, Sutekh or Seteh) was originally the god of the desert, storms, darkness, evil and chaos. As such, Set, leading the shady town of Necropolis, fits the reference well.
 * His reference to the god "Set" is also reflected in his personality; although not necessarily evil he tends to be very aggressive.
 * In Fallout concept art, a person named Rake was supposed to be the Necropolis's leader.
