Why These Connect
The narrative assertion
"The Keeper's initial tasking of the Doctor (beat_94b18b5570bd3ed4) specifically mentions investigating the Melkur, immediately linking the 'all-pervading evil' to the calcified entity, which is then explored in detail by the Keeper in the next scene (beat_6455f93d70054b73)."
About Causal Connections
A directly causes B. The first event sets forces in motion that produce the second. These are the load-bearing connections of plot—remove one and the story structure collapses.
