The day has come, which the Light Ones feared so much, which the Dark Ones dreamed of for centuries. The Great Mother of Serpents performed a ritual, the Fire Dragon freed itself from ancient fetters and began its incarnation in our world. A terrible battle is coming between good and evil. Sinister, mavkas, bats, fiery wolves filled Klykovo, laid siege to the clock tower, where three students of "Pandemonium" maintain a protective dome over the city and its environs. As long as the dome is intact, as long as the Light Ones hold the line, evil spirits will not leave the city, but help will not come from St. Erinburg either. Old friends and enemies reveal their cards, the immortals perish, the dead come to life, Ophiuchus is exposed. But most importantly, Timothy seems to know how to destroy the Fire Dragon.
