`wowrealm`: Get or set the server's default WoW realm.

    When the realm suffix is omitted from a character name when using the `wow`
    command, the default realm set using this command will be used.

    You must have the Manage Server permission to set the default realm.

    **Usage:**
        `wowrealm`: Get the server's default WoW realm, if it is set.
        `wowrealm REALM`: Set the server's default WoW realm to REALM.
