Maybe it means that the air is easier to breath.
That the nights are more restful, that peace descends and the spiders are no longer interested.
Perhaps it means the invaders see the doors and windows as tightly locked, that the other side is secure.
Instead of waiting for a weak spot in the armor, they disappear into the netherworld from which they were roused.
Called here only to encourage and thrive on disturbance.
Fear propelling fear, a long cycle it is to become closer to Well.
