Horizon was a male SandWing who was introduced in The Dragonet Prophecy. He was a soldier in Blaze's army during the War of SandWing Succession, but was later captured by Scarlet and forced to fight in the SkyWing arena. He was killed by Peril in combat.
The Dragonet Prophecy
After he and the other dragonets were imprisoned by Queen Scarlet, Clay was placed on a spire next to Horizon's. Horizon spent most of his time between matches pacing around angrily and lashing his tail, shaking the wires attached to him.
After four victories in the arena, Horizon was pitted against Peril. He attempted to fight her, but after realizing that it was impossible for him to win, he threw himself into her firescales for a quicker death, causing him to burn and die. This made Scarlet angry because such a quick match was disappointing, and Peril later explained to Clay that it was "poor form" for the SandWing to give up instead of fighting to the death and that Peril should have shoved him away to make the battle longer and more exciting.
