Sanity Field

Apparently, the Flowers are trying to reduce the number of Agents lost to insanity. Whether it's working is anybody's guess.

"You know how they have those fake windows in the Ministry of Magic?... Well, Upstairs maintains something similar – an imitation sanity field that follows every agent around. It's like the SEP field attached to the patch on your sleeve, but this doesn't come off. It wears thin very quickly, though; being used too much, and all."
