The only person to ever know Gog and Gasha's story was Rad. Sometime during part one of Lud, Rad was helping Gog perform maintenance on some components in his head and Rad received an electrical shock that literally planted a memory from Gog into Rad's mind. Rad never shared this memory with anyone else, possibly due to the personal nature of the memory.
So here it is.
Gog can't remember much of his childhood before he was re-constructed with cybernetics. All he can recall of his parents was that they were skilled mechanics and brilliant engineers. They knew Gog was gifted with the affinity to manipulate metal and steel with his will, and they nurtured his talents as any good parent would.
The Alon first arrived on Lud when Gog was still very young. At the time, Lud was teaming with gifted, and the ensuing raid was the most violent skirmish in the city's history.
Desperate to keep Gog safe, his parents were placed on the losing side of the fight. Tragically, they were unable to keep the Alon away from their son, and the Alon apprehended the young Gog. Defiant and powerful, Gog fought back. Unfortunately, the Alon were not defeated and Gog was killed and his body mutilated in the resulting battle.
The next thing Gog can remember, he had been rebuilt and given new life, but his parents were gone. Gog never found out what actually happened to them, but he suspects that they lost their lives protecting him a second time. Gog took over a small, abandoned shop that his parents had worked in and began his life alone. Every so often, he would upgrade himself to accommodate his still-growing human body.
In the aftermath of the Alon's raid, Gog was able to salvage some of their technology, and despite the fact that he never fully understood their advanced tech, he was able to reverse their tracking signal to create a 'blind spot' of sorts around Lud.
Years later, he found a very young girl stuck in a tree. He spent the entire year searching for her parents, and only gave up well after Lud had docked at it's annual destination. Gog named her Gasha, and took her into his home to live. They have been together ever since.
Inspired by the bravery and conviction of his parents, Gog now makes it his business to safely house any and all gifted he can each year.
