An employee of the Institute of Experimental History has been assigned no easy job — to wander through parallel realities and restore violated historical justice. And now he receives a new task. The mission is this: he must break through to the end of the merry 12th century and rescue from captivity a bad monarch, a bad poet, and the noblest of knights — Richard the Lionheart!
His experience, a cunning partner nicknamed Fox, and an ancient sword forged by the Scandinavian gods and named Battle-Seeker will come to his aid. Not bad! But what awaits the hero — do you think it is only dangerous adventures? Only an encounter with a very ambiguous magician? Not at all, that is only the beginning!
