Iceback Leviathan
The Iceback Leviathan is among the largest and most formidable creatures to prowl the frigid waters of Northguard, a towering behemoth of muscle, blubber, and ancient instinct. Towering over even the largest whaling ships, these creatures are easily identified by the thick, jagged ridges of frozen keratin and ice that line their massive backs—natural armor formed over centuries of carving through glaciers and enduring the brutal northern storms. Their deep, sonorous calls can be heard reverberating through the mist-covered fjords, an eerie chorus that signals their return to summer feeding grounds. Despite their ponderous movements, Icebacks are far from docile; a single swing of their barnacle-encrusted tails can send smaller vessels reeling, and they have been known to retaliate fiercely against hunters who fail to bring them down with precision.
Revered by Northguard’s whaling clans as both a prize and a terror, the Iceback Leviathan is hunted for its unparalleled stores of rich, slow-burning blubber, capable of fueling lanterns and hearths for months on end. Their meat, though tough and thick with fat, is considered a staple for those willing to endure the harsh climate, while their colossal bones are carved into everything from ship keels to the ceremonial weapons of the most honored warriors. Some claim that the oldest Icebacks, those who have outlived generations of hunters, possess a strange, knowing intelligence—that they remember those who come for them, and that a hunt gone awry can lead to a vendetta carried across the ages. Many seasoned whalers refuse to strike at an Iceback more than once in their lifetime, fearing the wrath of a leviathan that has survived past the harpoons of their fathers and grandfathers.
Legends abound of Icebacks that have lived for centuries, growing to such monstrous proportions that they are mistaken for drifting icebergs until it is far too late. Some of the oldest sagas tell of a leviathan large enough to capsize an entire fleet, dragging sailors into the frozen abyss with a single, mournful dive. Whether these tales are mere superstition or hold some glimmer of truth, none can say for certain—but every whaling season, as the hunting ships set sail into the icy expanse, there is always one ship that never returns.

Basic Information
Biological Traits
The Iceback Leviathan is an immense and long-lived cetacean, uniquely adapted to survive in the frigid waters of Northguard’s northernmost seas. These creatures are among the largest known marine animals, with adults reaching an average length of 130 to 150 feet (39.6 to 45.7 meters) and the most ancient specimens rumored to exceed 170 feet (51.8 meters). Their weight ranges from 700,000 to 950,000 pounds (317,500 to 430,900 kg), with some outliers surpassing a million pounds. Unlike most whales, Icebacks do not reach their full size until well into their second century, with growth rates slowing significantly after their first hundred years.
Males and females exhibit slight sexual dimorphism, with females being slightly larger and heavier on average, particularly in their midsections due to thicker layers of insulating blubber. This additional mass allows them to survive in deeper, colder waters where they birth their calves. The species is distinguished by its thick, jagged dorsal ridges, composed of hardened keratin and ice formations, which grow more pronounced with age. These natural ice-covered "spines" help the leviathan break through frozen waters and provide defensive reinforcement against the immense predators of the abyss.
Iceback Leviathans are extraordinarily long-lived, with an average lifespan of 350 to 500 years, though the oldest recorded specimen, according to Northguard whaling logs, was estimated to be over 600 years old. Their bodies show a remarkable ability to heal from wounds, even regenerating some forms of damaged tissue over decades. Some scholars theorize that this regenerative capability contributes to their longevity, making them far more resilient to age-related decline than other cetaceans. However, despite their incredible endurance, their massive size and thick skin do not make them invulnerable—persistent whalers and the occasional titanic sea predator are among the few threats that can bring down these ancient giants.

"To see an Iceback Leviathan breach the frozen sea is to witness the raw power of the North itself—ancient, unyielding, and utterly indifferent to the fleeting struggles of men. You don’t hunt them; you gamble your life against theirs and pray the sea favors you." — Victoria Pendrake
