The familiar world collapsed, the city went underground and people left it. Those who did not have time became prey, unable to resist the force growing stronger day by day. Ordinary weapons are useless against ethereal forces; ancient evil cannot be destroyed with lead. Salvation lies in a different force, a different power - the one that the ancestors owned, that they preserved for people at the cost of their lives. But he still needs to be found. You need to find the hiding place and get an antidote to witchcraft by solving the puzzle that the first guards of the city left for their descendants. To do this, Denis and the soldiers of the Special Department will have to penetrate into the very center of the city. You will have to bypass traps, go through battles with incorporeal creatures and perform a ritual that will forever cleanse the city and close the gates to incorporeal creatures summoned by ancient power from the ravaged graves.
