Los

Los is a ghoul city somewhere in the eastern part of the former Los Angeles. It covers whole dock area and a heavely damaged bridge. It is inhabited by ghoul fanatics known as the Church of the Lost, who kill all humans who wander into the city limits and even kidnap some for their bloody rituals. The leader of this cult is Blake, a horror and an astonishment, a powerful, but insane warrior. The cult itself is very dangerous, as they use poison dogs, laser weapons and suicide bombers to defeat their enemies. However, not all of the ghouls are bloodthirsty killers.

Some of them are friendly and lives on the western part of the city's bridge. There you can find an engeneer, Giese, a merchant Hieronymus and old traveller Harold, but all he does is send you on a quest to find his missing body parts. Another friendly ghoul and a merchant, Salieri, is found nearby, in the docks. The ghouls of Los manage a Gladiator Pit, an arena where anyone could fight for money and the crowd's fun.

The Secret Vault built by Vault-Tec for top secret Forced Evolutionary Virus research can be found under Los. It is a holy mission of Blake and his cult to protect this Vault, as they consider it to hold an evil inside, that should never be released.

Everything changes in Los when an army of Super Mutants, led by Attis, attacks the city. They quickly make their way to the only remaining entrance to the Vault and take it over, leaving only few of their soldiers to protect the entrance from raging ghoul fanatics. Some time later, a Brotherhood of Steel forces come, aiming to battle Attis's army. They were stuck between the ghoul fanatics and Super Mutants soldiers, and soon only Rhombus, who led this force, survived, being captured by Blake.
