Hailing from the tundras of Valeminor, Horus knew no more than to fend for himself in a seemingly endless winter. His cold demeanor developed as such, and he would often rival other wyverns and monsters from the abandoned ruins of the Old Kingdom for a morsel of food or territory. Eventually, competition drove him out of his den and he was forced to flee to Crithus, seeking no solace from the Elements who abandoned their species. There, he met his first and only companion Echoe, a bright and welcoming spinosaur who saw past his cold exterior.

Outside of his interactions with Echoe, Horus guards their new home with fervid determination, a habit long formed from his life before. He expresses his affection with protection, servitude, and the occasional impressive hunt to feast. As it turns out, being a dragon amongst dinosaurs makes for an unfair advantage, regardless of their curious, mechanical innovations.
