Urgana the Unkown and Picatrix

In the 12th century, the lost Star Knight Amadis had many adventures. Some of these involved the evil wizard Arcalaus and his nemesis, the magician Urganda. Late that century, a fight between Arcalaus and Urganda created a magical explosion which projected them through time, forcing them into the year 1995. After a period of adjustment, Arcalaus maintained his evil ways, but adopted the fashions of this new time period and christened himself Picatrix after a grimoire from his time. Rather than operating publicly, Urganda chose to indirectly affect events, supporting heroes in their fight for justice as she did in her own time. The pair have continued their war with one another, but mostly operating behind the scenes, like chessmasters playing heroes against villains to further their ends.
