Flying over the icy wastes near the Frozen Ocean, the combination of the cold and exhaustion from nearly dying (as well as potential lingering effects of the dart), caused the Beast to begin to lose altitude and crash.

As the Mirror Demon pursued Tom and Elenna to Gorgonia, Kapra used her serpentine magic to cover Ferno and the other Good Beasts in binding snakes. Just before the Fire Dragon caught the Beast Guard, Tom pulled Ferno's flight path to one side, allowing him to graze a wing with his sword, sending Grashkor spiralling into the water, where Epos dropped the final standing tower of the prison on him. The Fire Dragon patrols the river and makes sure the southern towns of the kingdom are never flooded.

The Fire Dragon released flame, being deftly avoided by the Flame Bird, who struck the tip of Ferno's tail with a fireball. Ferno later joined with the five other Good Beasts on the shore of the Western Ocean to help summon Spiros, with the Fire Dragon thumping the ground with his tail. With the artefact free, Ferno released more flame, incinerating Claw before flying away as the warrior grabbed the Golden Chainmail.

He began to advance on Nemico, eventually forcing him off of the cliff, although he was caught by Tom, merging them and restoring Tom's whole soul. The Beast's main role is protecting southern Avantia and ensuring the population of the region are free from danger.The fires he created was the reason Tom was sent to the City, which would start him down his journey to become a Master of the Beasts. When the group stopped to help Seth, Ferno stayed out the fight with Epos, watching but not attacking. The Fire Dragon took aim and released a jet of flame at the dark wizard, incinerating Malvel and killing him instantly. Like the other Good Beasts, Ferno attended Taladon's funeral in spirit, channelling his grief and anguish through his token in Tom's shield as the former Master of the Beasts was taken into the Gallery of Tombs.

As he and Elenna were hurrying off the Beast, Ferno sensed them and roared in anger and began to shift and rear up, with the Avantians throwing themselves clear. Maximus chose Ferno to be the first Beast to serve him in the Battle of the Beasts, and used dark magic to tame him and bend him to his will. The Beast explained he was unaware what had come over him, with Tom quickly explaining what the venom had done to him before the group left to pursue Falkor and Berric.The Fire Dragon drew close to Tom, who leapt from his Henkrallian steed onto the back of the Good Beast. His burning breath is described to be as hot as molten lava and is powerful enough to incinerate Claw and kill Malvel. Enhanced Durability: Ferno has incredible durability, as he can survive being thrown through walls, slammed into the ground by Nanook, falling from great heights and being stabbed by Kyrax (although he did have to recover for a few minutes afterwards). When Malvel dispatched Arax to corrupt Aduro and kill Tom in battle, he based himself in the mountain caves near where Ferno made his home. The Beast began to plummet, but the passengers managed to leap off safely before the Fire Dragon struck the ground.
