Aniela

Aniela is Polish princess. She comes to Elsinore to marry Prince Hamlet by the choice of Prince Claudius. Prince not King because day after funeral the deceased king appeared not before Hamlet but before his brother. Old Hamlet threatened Cladius into crowning young Hamlet and into work for the benefit of Denmark. While Claudius agreed at first, he still wouldn't be himself not trying to deceive his brother. He seeks help of the witch, Ruffiana, who points at Aniela as future queen. Claudius brings Aniela in, and then all the hell breaks loose...

I don't have to add that Rufiana and Aniela are in fact the same person, right?
