Arche means the source that still beats and from it flows the world. Christians can call God by the name of Arche. He is also the one who was in the beginning, from him the world originated and he keeps this world alive. In the Middle Ages, the source was also sought in the philosopher's stone - it, too, was supposed to act as the golden rule and only a side effect of its action was to be transmutation - that is, turning lead into gold. In the film, Arche is a mysterious Source through which time and space can be influenced.
