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 is known for being a pretty rude and unpleasant fellow, whose colorful vocabulary contains a lot of use of the word "dirtnap" and the phrase "standing in my shadow". 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.

Interactions with the player character
Set is annoyed at the Super Mutant presence in Necropolis and tries 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 in possession of the Water Chip.

Appearances
Set appeared in the first Fallout game and died during it, in the Fallout timeline. 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) is an ancient god, who was originally the god of the desert, Storms, Darkness, and Chaos, as such the character in fallout's name may be a reference. Also the Greeks conneted the Ancient Egyptian Set with the creature Typhon as both were associated with storms.
