Ghoul sentry

The ghoul sentries are guards in Necropolis in 2161.

Background
They stand outside the Hall of the Dead, guarding it from intruders. Nothing is known about them aside from being guards that are extremely loyal to Set and their city.

The other sentry is a glowing one, in front of the entrance to Vault 12, and will become hostile towards anyone trying to enter.

Other interactions
If the player talks to them while trying to enter the Hall of the Dead, they will tell him to go away, and that they don't want their kind around there. Even though they say that, the Chose One can run past them without any repercussions.

Appearances
The ghoul sentries appear only in Fallout.
