Although the actual decline of the Ottoman Empire wouldn't be evident until the 1800s, the Warehouse was located here only during the reign of Suleiman the Magnificent. After his death, military and political stagnation indicated to the Regents of the time that a move would be prudent.
On a rainy day at the Warehouse, Pete accidentally triggers an artifact that transforms the team into two-dimensional diorama versions of themselves, and returns the Warehouse to its original, unstable design.
Who knew Claudia had those moves?! OK, so maybe they're artifact-induced, but we're so in love with the spangles, we don't care!
