While looking for something else, I stumbled upon an intriguing snippet: [here] and [here]
If Google can be believed, this has only been echoed by these two players. It’s not on the wiki, so I guess it’s something extremely rare and/or Fate-locked. Does anyone have an idea to which storylet this belongs/where it can be found?
I think it’s Fate-locked, though I’m not sure what snippet it is exactly. Maybe a Rare success for eradicating your Nightmares on a moment’s peace? That would be my guess.
