As the Beast still writhed, Tom entered and turned the key, causing the collar to vanish and release Ferno. 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. Ferno's fire was also strong enough to melt Nemico's leather shield and fling Arax against a rough mountainside. Durability Limits: Ferno's durability has limits, as seen when he got knocked out by a flaming boulder.

After Tom had freed Raffkor, he then had to get to the City of Snakes to get the next ingredient and free Vislak.He was later awoken by Lyra using the potion she and Daltec had developed to reverse the spell as Daltec awoke Sepron. As Ferno approached the City of Snakes, two sand twisters rose from the ground (possibly created by Kensa's magic). The Beast rose up, flung his wings wide, began to build up fire, and released the jet of flame at Tom, who rolled aside before using his shield to negate the fire. Ferno then stayed to watch Tom be inducted as the new Master of the Beasts, replacing the deceased Taladon.

The Beast pinned his foe to the ground, raking his claws across his chest and making significant gashes. Ferno wished to continue helping Tom, however Tom told him to remain safe, worried Ferno could be cursed by Kensa if he stayed. After Sam lost his sword, Ferno was guided down to strike, heading for the lake as Epos tried to lure him into the water, but pulled off when Lara found the sword in the water and recovered it, passing it to Sam as Ferno adjusted and approached. Elenna rushed to her wolf, aggravating the Fire Dragon who roared out and pulled his head back to strike.As one of the Six Good Beasts of Avantia, Ferno was one of the targets of Malvel's attack on Avantia. As Tom forged the sword the two Beasts battled outside the City walls, with Kyrax managing to come up on top, throwing Ferno at the walls, smashing a hole for him to enter before leaving the dragon to bleed on the cobbles.
