The Mask of Loki
The wizard thinks he's in control. The gods think that's funny...
It started in the 12th century when their avatars first joined in
battle. On that occasion the sorcerous Hasan al Sabah, the first and
Chief Assassin won handily against Thomas Amnet, Knight Templar and
White Magician. There have been many duels since then, and in each the
undying Arab has ended the life of Loki's avatar. But each time the
avatar is reborn, and the Assassin tires...
It is now the 21st century. Loki's time approaches, and Ahriman, Lord of Darkness, must fall.
