I feel like Magolor's species tend to have litters of two to three pups, with Magolor and Gamiel being a litter of two. Magolor was a runt, smaller than he's meant to be and with stunted, flightless wings. He was bullied for this by other pups and his family probably did not handle it as gracefully as they could have either, so it did indeed drive a wedge between him and the others from an early age

He learned to make himself bigger, literally and figuratively; he was loud, he was rambunctious, he trained himself to float higher to appear taller. There was no meaningful change in how he was treated when he tried to be good, so he decided to stop trying and fully embrace his label as "the problem child". He schemed to get what he wanted, he learned magic to feel powerful, he wreaked havoc on the people who dared continue to torment him. Giving gets you nothing, you've got to take, take, take.

And eventually he left altogether. It may have been after a fight, or he may have simply vanished one night, never to return to that place again. He carried his childhood lessons with him, though. He continued to lie, scheme, and steal his way through life, all the while bolstering his magical abilities so he could get out of the many situations he landed himself in. He would read too, when he had the time, about magic and artifacts and legends. Most of it was nonsense. Imagine, a crown that gives you limitless power! What bullshit. The things he could do with something like that, though… No one would ever call him a runt again, that's for sure!

After some years, a particularly bad string of luck landed him on the miserable planet of Halcandra. He had crashed, or perhaps been marooned; either way, he was stranded. He scoured the small planet for something, anything that might let him escape, eventually finding, of all things, a Starcutter!! It was broken down and hadn't seen maintenance in years, but there was a scrapyard nearby. Surely he could fix her up. He'd dabbled in engineering as a hobby, and he'd read about these things before. No reason not to try.

And as he was scavenging for parts one night, he caught sight of a dragon flying through the sky, wearing a… well, the rest is a bit of a blur for him.
