The gods are playing games. You lost a duel to a black avatar, but the gods threw your soul into one of the alternative worlds, into the body of... an American schoolboy! This world is interesting - it has both the USA and the Republic of Ingushetia, but it also has magic, and strong magic, as well as clans of witches, vampires, werewolves and other creatures. This is where practicing magic, which the Magi taught you, will come in handy... But don’t think that they will leave you alone.
