Arianka

In the distant past, Arianka was defeated and imprisoned by an unnamed Chaos God and it is said that she lies in a crystal coffin, hidden somewhere in the Old World. Many places have claimed to have found her coffin over the centuries, the most recent, according to rumour, being Praag. It is also said that she can be freed from her coffin only by means of some crystal keys, whose location has never been found; it is not even known how many keys there are and whether they are hidden together or separately.
