Why These Connect
The narrative assertion
"Maren’s decision to confront the Time Lord by forming a ritual circle directly escalates the supernatural stakes in Karn. This decision, though unseen, is the unseen trigger for the telekinetic storm that forces the Doctor and Sarah into Solon’s castle—and into the path of Solon’s trap."
