Magic Circle (virtual worlds)
<p>"All play moves and has its being within a play-ground marked off beforehand either materially or ideally, deliberately or as a matter of course. Just as there is no formal difference between play and ritual, so the 'consecrated spot' cannot be formally distinguished from the play-ground. The arena, the card-table, the magic circle, the temple, the stage, the screen, the tennis court, the court of justice, etc, are all in form and function play-grounds, i.e. forbidden spots, isolated, hedged round, hallowed, within which special rules obtain. All are temporary worlds within the ordinary world, dedicated to the performance of an act apart.<sup id="cite_ref-4" class="reference"><a href="https://en.wikipedia.org/wiki/Magic_Circle_%28virtual_worlds%29#cite_note-4">[4]</a>"</sup></p>
