Diagon had slaved 99 dimensions, he attempted to rule this one, Costi was an immortal so he never died, he discovered an artifact which when he touched it, attached to his chest. Eons ago, the ancient galvan built another devich which was called Goodtrix, it was only made to be secured to the good, so Costin found it and used it to protect his people if they were in need. In 953 A.D., Diagon came to his planet and used his powers to turn all the ancient vaxasaurians into vaxasaurians, everyone was affected execpt for Costin who was praticing one of his aliens. Diagon got the chance and sended his Lucubra Army to destroy them.

I was researching when I came to this planet which is called Terradino, I looked at the condition of the planet when I saw some Vaxasaurians fighting the lucubras. All of the vaxasaurians execpt Costin who defeats all of them, when he is tired, I come and ask him "Are you tired". He says you very small, I ask him, do you want any help, he says if you have an equipment then you can give it to me. i gave him ascalon and asked him to return as soon as he defeats the creature, He shows them one of Diagon's forms which gets defeated, Costin throws the sword on his eyes which hurt him, he then uses magic which traps Diagon from entering our dimension, he then returns it back to Azmuth and says Thank You. He finishes his story.

After hearing this, George asked that, you kept Ascalon with you until you researched earth. Azmuthn says Yes. Azmuth sees space and tells them he was the savoiur of the terradino's and thewhole universe.
