The Repository of the Improbable was a location on the Braxiatel Collection.
The curator of the Repository was R.F. Wilburton. Housed in the Repository were problematic items that couldn't be dismissed as forgeries.
Bernice Summerfield visited the Repository on an errand for Irving Braxiatel, and while there, she couldn't resist touching a joining stone from Goron IV. (PROSE: The Door into Bedlam)
