A true epilogue is removed from the story in time or space. That's the reason it is called an 'Epilogue'; the label serves to alert the reader that the story itself is over, but we are going to now see a distant result or consequence of that story.

Even if your novel occurs in an unfamiliar setting in which all the customs and surroundings will seem strange to your reader, it's still better to start with action. The reason for this is simple. If the reader wanted an explanation of milieu, he would read nonfiction. He doesn't want information. He wants a story.
