Zara sighed, thinking, then said "I recently found that there are a group of elves who forge magic swords... If you can get anything with magic properties that can be made into a sword, perhaps it will keep Zero's demonic dragon side locked inside him. The only problem with this, however, is that when in battle, he must never let go of said sword, otherwise, if he lets go of the sword and comes into a broken state, which is the state lingering between life and death, his dragon side will come out, and thus he will be unstoppable, and as said before, with repeated transformations to this demonic dragon side of his, he would, eventually, lose his soul to that demonic dragon that, so far, lays dormant within him." Zara said, a blank look on her face. "The sword would protect his soul, but you'd need to make something that would, considerably, protect his body, like a type of armor."
Ziggy nodded, "What do you think would be needed to forge such a sword or armor?"
"I would suggest Mithril for the armor, black mithril is best, though it is incredibly rare, more so than normal Mithril." Zara said. "As for the sword, I would suggest either a demon fang or a demon bone, and some silver as well, to give it a more more sword-like look rather than a bone-look, make it look more intimidating." She said, "That way, not many enemies would come after him as long as he keeps a hold on the sword, or keeps it close to him."
