How sharp should the transition be, from the opening in the prologue, to the main events in the story?
There is a part where things really get rolling, but there is some action before. For instance, the news of the empress killing all her servants one night to hide -- something. (Not, as a sage soul observed, a wise way to do it.)
But action moves a lot faster in the -- week, maybe? -- where the bulk of the drama occurs.
