You Akroxs, the archimagus of fire and ice. Long time ago you have called great demons, masters of fire for yourself in a service, in exchange for the soul. But when payment time has come, you have not wished to give the most valuable that is at you. And you have gone to their house to win them and not to be more dependent on them. Whether you will to win them? Or you will for ever doom the soul to a fiery torment?
