In a far-off corner of the galaxy, a mysterious portal exists that connects distant planetary systems together. Disguised as an ordinary basin, this portal is invisible to the naked eye. However, those who know of its existence and possess the 'key' to unlock it can travel between worlds with ease.

For this reason it is remarkably dangerous and is therefore guarded by a powerful wizard, who uses his magic to keep its secrets hidden from those who seek to misuse its power - many do misuse it however, and have paid the ultimate price; stuck en-route, misdirected or simply not making the destination, with no way to return.

Despite the danger, adventurous travelers and cunning thieves alike seek to find and unlock the portal, lured by the promise of untold riches and untold dangers on the other side.
