Echoes of a distant battle. Muravyov K. N.

There is an enemy. Ancient and dangerous enemy. He is very strong and powerful. With forbidden and formidable magic. The magic that has long been forgot about in this world. The enemy, broken and expelled a few centuries ago, but who suddenly appeared again. And in the center of these events was Dim, an alien from another reality. He, by chance, as well as the efforts of agents of the local Union of states, was drawn into the fight against the new invasion of the old and dangerous enemy, finding himself on the very border of the war.
