Fallout 76 has introduced a lot of fun pieces of lore to the overall Fallout franchise. From a new location in Appalachia to playable Ghouls finally becoming a reality, Fallout 76 has staked its claim as an important entry in the series. The Appalachian mountains are filled with plenty of horrifying threats, but one of the most harrowing additions made to the series is the introduction of the Scorched Plague.
