[The Mask] What is The Mask, where did it come from and why does it seem to have power over other people?

It was a ceremonial mask that contained the Norse God Loki's spirit, who was the god of Mischief and Tricks. It can change the appearance and personality of the wearer, and bring out their inner desires and to a lesser extent those around him. They would have thought he was entertaining and started to dance as a result of the masks magic.
