The manor of Casl котц gradually gets swallowed by winter. A crack in the Sacred Aquamarine is miraculously healing over step by step; the students continue their studies. It seems the danger has passed. But why then do the oddities in the castle continue? Why has the Order invited the Guardians of Pre-Prime Chaos to Casl котц—and what are they searching for? What’s more, rumors have spread that the Mist Sea has started to move and is swallowing the village, one village at a time. As if all the frightening events from outside weren’t enough, the Coven, its friends, and other students of Casl котц will soon have to find out who Cernunn is and pass the next, most difficult trial. Who is he? Because not a word about him is found in any of the books in Casl котц’s oldest library! The friends must uncover a new secret and deepen their self-knowledge and struggle with their own fears and doubts.
