My Best Friend Is An Eldritch Horror Light Novel Vol 4

Magic and madness continue in MY BEST FRIEND IS AN ELDRITCH HORROR (Light Novel) VOL. 4! Blackmist is under attack! And that's the least of Damien's problems. He's managed to survive all the challenges thrown at him, and — with Henry and Sylph by his side — he might even make it through the challenges that come with having an insane ex-frontline mage as his professor. But forces that have lurked at the edge of the Void for countless Cycles have started to move, and their power is growing with every passing day. As more of the truth behind the Void and its purpose on the Mortal Plane is unveiled, Damien is forced to face the truth that the Cycle--the foundation of their reality--may need to be reset.
