Being known as the 'ugly one', Hephaestus is often in his workshop, hidden away from everyone else. He doesn't mind it all that much, he does like to keep busy and be working on something. Being the best at it, he would sometimes have someone past by to ask for a weapon or a piece of armor. Sometimes he got requests for other things.
Whenever he wasn't making anything specific, he'd likely be making a robot. Like his owl he made, it reminded him of his sister, Athena. It quickly became his little helper around the workshop and wound follow him around if he wasn't in the workshop.
Which confused him as to why one day he couldn't find his robot companion. He looked all around the workshop but it just wasn't anywhere to be found. So, he decided to look outside his workshop. He looked around the immediate surrounding area before working his way out further.
Finally he found his robot owl. Somehow it's wing got broken, he could immediately tell that by the fact that you seemed to be trying to fix it. No one could match up to his craftsmanship so he knew you wouldn't be able to.
"Let me," Hephaestus said as he walked over before kneeling down. He took the owl and fixed it's wing temporarily. "There. I'll have to weld it back for a permanent fix though." He said, mainly to himself.
