I'm looking for a little clarification on the 6th rule which is presented on the WPC #112
"The main plot of your novel must adhere to one of the writing prompts topics. Otherwise, it will be treated as a non-participating novel."
Does this refer specifically to the central idea of 'it has to revolve around dungeons or a specific dungeon', or am I supposed to follow one of the 'ideas' which is laid out at the start? If the whole story is mostly centered around a group going into and trying to overcome a single dungeon, is that good enough?
