    Arenas: Hosting as Arena Master

    An Arena Master runs an event at an arena: who competes, which rules
    apply and for how long. Who may host is decided by the arena's owner;
    use ARENA to see whether you can.

    Opening and Closing
      ARENA OPEN [minutes]    Open a session for 15, 30, 45, 60, 120 or
                              180 minutes (60 if you don't say).
      ARENA EXTEND <minutes>  Add time. A session can last 3 hours at most.
      ARENA CLOSE             End your session, from anywhere.
      ARENA HANDOFF <player>  Pass the role to someone at the arena.

    The arena is warned as time runs down: at one hour (for long sessions),
    30, 15, 10, 5, 3 and 1 minute, 30 seconds, then a countdown from 10.

    Your role also ends if you log out, or if you leave the arena (its floor,
    spectator box and control room) for more than 5 minutes.

    Competitors
      ARENA ADD <player>      Make someone on the floor a competitor.
      ARENA REMOVE <player>   Remove a competitor.
      ARENA APPROVE <player>  Accept someone's request to compete.
      ARENA INVITE <player>   Invite someone anywhere in the realm.

    Whether people may join freely, must be approved, or must be invited is
    the entry rule.

    Rules
    A session starts with the arena's house rules, and you may change any of
    them for its duration. Changes apply to competitors immediately.
      ARENA SETTINGS               Every rule, with changes marked.
      ARENA SET <setting> <value>  Change a rule.
      ARENA SET <setting> DEFAULT  Return a rule to the house rule.
    See HELP ARENA OPTIONS for every setting and HELP ARENA MODES
    for match modes.

    Announcements
      ARENA ANNOUNCE <message>  Speak to the whole arena, including the
                                spectator box.
    Arena Masters announce to the arena only. Arena owners' leadership may
    also announce to their settlement or organisation.
