Added a new arena - the Arcaneum

The Arcaneum is a small arena for gladiator fights, which can accommodate no more than 6 players.

The prototype for creating the location was a reference from the TV series "Spartacus: Blood and Sand". We tried to copy all the elements in as much detail as possible: wooden walls, places for guards, stands, sunshades, etc. The audience will be located as close as possible to the players, which creates a sense of privacy. The location turned out to be very atmospheric and accurately conveys the emotions of the gladiator fight
