The Edgerammer is a massive coastal aquatic creature of Kela's polar shelves, 12 to 14 meters long and weighing 10 to 15 tonnes, its streamlined body and battering-ram head built for explosive collisions that shatter ice and hulls alike. Named for mistaking ships for rival Edgerammers, it charges coastal routes and shelves with unerring force, creating navigational hazards and reshaping the frozen frontier. Non-aggressive toward humans directly but destructive by nature, it reproduces rapidly and lives 80 to 120 years.
Actively hunted for its rich meat and oil, which is used in machines across Geba, the Edgerammer sustains polar economies with hides used for durable gear and fashion. The Empire manages wild herds in submerged barriers spanning hundreds of kilometers. The Kela Maritime Guild bred a smaller variant without the ramming head, transforming it into a dedicated food source for polar operations that does not destroy the infrastructure it is being raised alongside.
