Polmear & Plenty's Inconceivable Circus
From The Fifth City Wiki
"A travelling circus has settled here, too afraid to go further and too afraid to turn back. Its clanking, gaudy locomotive scavenges such audiences as it can from nearby homesteads and delivers them for an evening of shabby desperate big-top magic."

Polmear & Plenty's Inconceivable Circus, perhaps the successor to Mrs Plenty's Carnival in Fallen London, has become unfortunately stranded in the Reach. (Is it possible to free them?)
