The History of Tournaments in Habitat Tournament play in the Arcade began on a rather bizarre note when Mixolydian, Keeper of the Trans-dimensional Vault, was turned into a tree by Dada Salesh, noted eccentric wizard, after Salesh accused the Vault-keeper of cheating at backgammon in the first (and, understandably, last) Populopolis Backgammon Tournament.
Salesh, full of remorse at his deed but unable to recall the spell required to return his friend to avatar form, subsequently placed the leaf-laden Vault-keeper in a densely wooded area, hoping to hide either his short- tempered nature or his poor memory of magic spells.
The Vault-keeper's absence was soon discovered, however, as he had in his possession at the time the only known keys to the Vault -- a chamber with 10 safes containing vast amounts of jewels, magic items, tokens and other things of great value -- as well as the knowledge of when and where the Trans- dimensional doorway (the only path to the Vault) will appear in Habitat ("Even the great Salesh does not know how to find the Trans-dimensional doorway," the Vault-keeper was rumored to have said shortly before his mouth became a knot).
Since the Trans-dimensional doorway only appears in Habitat once every 1625 years (that's 119 years for humans, 17 years for their dogs), the Vault remains hidden to this day, though it is rumored that avatars who can find the Vault-keeper's wooden form can elicit from him a key to the Vault and even some clue as to where the Trans- dimensional doorway will next appear in Habitat (if you're persistent).
Meanwhile, Tournament play in the Arcade has been rather sparse, though it is hoped that the recent boom in Populopolis will bring this sort of organized, relatively safe entertainment back to our fair town.
