In the deepest forest in Transylvania, Zeno was a member of the Blue Spirit Dragon and he has always been following the footsteps of his ancestors' natural land. Unlike any tribesman to protect the forests, Zeno wanted to see the world for what it is looks like on outside of the forest but he was force to stay and watch over the forest from undesirable evil forces.
Until one night, the Ancient Trees of Nine Elements have turned into rotten trees when someone murdered the master who is the only one who can maintain the balance. Zeno heard the terrible news that the forest, even his home village, is left unprotected and he's eager to join the pack to protect their homes but he was ordered to stay and not to go outside. Zeno was disappointed but until the elder villager came to him and told that he has the Mark of the Dragonsnake; which means he can leave the village to restore the harmony of nature and balance, even though going against the wishes from other leaders. Zeno was excited as he left off the adventure to save the forest before Chaos consumes it.
Zeno have travelled the Batten Woods where others have already left to find and restore the ancient trees. As he's wandering around the middle of the forest, he was encountered by Fire-Fang of the Fire Spirit Bats and the pack consisted with Green-Blade, Sun-Wolf, Moonlight, Water-Bat, Batground, Sable Wolf, Iron Moon, Shadow Moon, and White Moon who was the leader of the pack at that time. After the encounter, Zeno joined the pack and they agreed with him as long he will listen to White Moon in a strict rule of the pack. The pack are heading to the Cavern of the Spirit Dragon where their first destination of claiming the power to save the forest as they're passing through the Feral Bat Woods. As they've entered the Feral Bat Woods, they've walked into a trap and captured by the Tazarek Feral Vampire tribesmen but they were freed and rescued by the Wild Vampiro Pack from the Razel Feral Vampire Tribe. After they were freed, the pack were brought to their village deeper in the forest where they can rest for a while. On the next night, the pack is needed for their help of defeating the Tazarek Feral Vampire and their leader, the evil vampire feral witch-queen, Tazeria, in the exchange of the shortest path to the Cavern of the Spirit Dragon, a Planegate.

At the prison cell in the temple, Zeno was chosen to led the pack by White Moon as he was unable to move while recovering. Zeno doubt himself with responsibility but he won't waver his faith and hope to stop Tez from completing his evil plan. Thankfully, as he had an idea to escape from their cell, they've used their Aura Form for temporally use to escape and succeed. Zeno and his pack race against time to stop Tez while White Moon is escorted to escape the temple by Iron Moon. They've fought their way to the ritual chamber where Tez was about to unleash Chaos across the forests and managed to stop the ritual as Zeno challenged his arch-rival and nemesis for the power of the Ancient Trees with his life and soul. With the challenge accepted, Zeno witnessed Tez's Chaos Aura Form of a Chaotic Spirit Dragon and Zeno fought his rival into the sky after he transformed into a dragon. The battle was fierce and harsh but brutal as Zeno was beaten down and grabbed by his sharp claw. Struggle to break, Zeno was in near death until his full power of his Aura was unlocked, giving him more strength to defeat him once and for all and then he struck his nemesis down with his strike attack.

After that, Zeno and his fellow pack and their ally, Feral Vampiro Pack, joined forces to defeat Thoragal and his forces and won as Velkan banished his ancient nemesis back from where he came.
