History
In the past, Heldalf was a general in Rolance back when he was a human. the kingdom he was in was being taken over by    Camlann  In order to avoid losses, Heldalf fled the scene while Hyland was attacking Origin Village. Michael, the previous shepard, had sent him to a life of solitude by sacrificing Mikleo at Maotelus' altar. After seeing his family dying, Heldalf attempted to commit suicide, but the curse had made him immortal and eventually accepted his malevolence. He vowed  is to end pain and suffering  for  all humans and seraphim in the entire world.

In the game, he was first encountered by Sorey in the battlefield known as Glaivend Basin. It was also revealed that he had Lady Maltron drive the events that have led to those wars between the two nations  then Lunarre stared the war up again and made it worst.

During the final battle, it had consisted of three phases. First, it was shown that Heldalf had absorbed Seraph Zenrus, which had angered Sorey and Mikleo into "settling things alone". Second, he had armatized with Maoteras into a full-scale monster, which had required power blasts from Mikleo (Luzrov Rulay), Edna (Hephsin Yulind), Zaveid (Wirukun Zavie), and Lailah (Fethmus Mioma) into stopping even his most devastating artes. Third, after falling downwards, he and Sorey had a final one-on-one match. While they clashed their mystic artes, Sorey's had outbested Heldalf and was eventually turned back into his human form.

In the end, Heldalf was sliced through by Sorey with his sword and then faded from existance.
