The Arena

Table Top Control Panel

Created from similar magic as an Instant Fortress, using the Mage's Magnificent Mansion as its primary magical source, The Arena is a magical extra dimensional space crafted by a planar traveler not of this prime material plane.  Unlike most magical items, The Arena is capable of attuning to more than one person and is greatly influenced by Mythic individuals and places. 

The Arena is an extra-dimensional dwelling that has two entrances on the plane from which the Arena was activated. The entry points looks like a shimmering hallways 5 feet wide and 12 feet high. Only those you designate may enter the Arena, and the portal is shut and filled with stone blocks of  magical force behind you when you enter. The controller may open it again from your own side at will. Once observers have passed beyond the entrance, the Arena opens up before them. The atmosphere is clean, fresh, and warm.

The place is furnished and contains sufficient foodstuffs to serve a nine-course banquet to a dozen people per level of the Arena's controller. A staff of near-transparent servants (as many as two per controller level), liveried and obedient, wait upon all who enter. The servants function as unseen servant spells except that they are visible and can go anywhere in the Arena, serving as an audience during battles. Since the place can be entered only through its special portal, outside conditions do not affect the Arena, nor do conditions inside it pass to the plane beyond.

When not in Arena form The Arena is a heavy dense table of unknown metal, the table measuring 40 inches in height, 24 inches across and 30 inches long, weighing 250lbs. The Arena if attuned to and being used by a non-mythic creature is a 240 feet across and 300 feet long (each square on the map is 10 feet).  The Arena's height is always 40 feet higher than the tallest creature. 

Mythic creatures attuned to The Arena may spend points for specific affects.  If more than one person attuned to The Arena attempts to activate any of its magical abilities, mythic and otherwise, the highest Mythic Tier, followed by highest level creature is considered its controller. 

1 Mythic Point: Triples the length and width of the Arena for 30 hours.  Doesn't affect height as the height of the arena is always 40 feet above the tallest creature or thing in the Arena.

1 Mythic Point: Comprehend Languages for everyone in the Arena for 1 hour

1 Mythic Point: Enlarge 1 willing creature per level of the individual that spent the mythic point for 2 hours

Other affects and powers will be revealed the longer one is attuned to The Arena
