Grayditch was once a small town found outside the D.C. area. When the bombs fell, most of the town was left standing. By the time the player leaves Vault 101 in 2277, it was used to house a small community. When the player arrives, you find that most of the inhabitants have been killed by Fire Ants. The only apparent survivor of the attack is a small boy, named Bryan Wilks.
Main Article: Those!
After the completion of the quest Those! all of the Fire Ants within Grayditch will attack each other and die, due to the Inhibitor Pulse sent out by either Doctor Lesko or the player. When the player returns to the surface, all of the Fire Ants will have already died.
