When Avengers Campus first opened, one of the entertainment highlights was the Doctor Strange: Mysteries of the Mystic Arts stage show, which featured an inter-dimensional encounter with the powerful Marvel sorcerer.  This was a popular show, but for never-completely-satisfactorily-explained reasons, it closed two years ago.  Though Dr. Stephen Strange does still make appearances here, the grounds are quieter nowadays, on account of the absence of this entertainment offering.  They're not as quiet as this after hours picture of the mystical courtyard, but they're not quite the bustle that they once were. After hours at the Ancient Sanctum are a tranquil and moody affair.
