Bad omens is a paper note in Fallout 76, introduced in the Expeditions: The Pitt update.
Location[]
The note can be found on the second floor of The Sanctum cathedral in The Pitt, during From Ashes to Fire. It is on a coffee table in the room where the Fanatic foreman is fought.
Transcript[]
Things remain peaceful here, while the chasm surrounding the cathedral grows wider and deeper. Supply runs are becoming more and more dangerous.
An illness is going around. If it weren't for the air it wouldn't be so bad. Olivia almost stopped breathing last night.
It was just after I saw a shadow outside the window. It looked like a person. Maybe it was nothing. We can't afford to have the Fanatics find us now.
I pray our safe haven remains as such, for as long as the Lord will grant us mercy.
