In a realm where the treacherous seas intertwine with the mysteries of ancient mythology, Marco Karta, a warrior outcast from the mythical city of Atlantis, is cast ashore to clash with a horde of Nephilim outside the enigmatic Van Helsing Manor. Imprisoned by Tars Van Helsing, a scholarly underling of monster cataloging, Marco's path converges with Sonya Thoris, a fierce captive warrior. Together, they forge an uneasy alliance to quell a sudden surge of mythical sea and land creatures, embarking on a perilous journey against insidious curses, rival pirates, and the shadowy malevolence of Echidna, a sinister force weaving its dark web across the realms.
