Decided to draw another important latias to the story of William and Amy's family.
For those that aren't already familiar with William's own story. He's a character created by
\n\t\t\t\t\tNocom and his story starts in his home universe. He was one of many experimental hybrids created by a facility to create legendary hybrids bred with non legendary pokemon to create pseudo legendaries who can breed more numerously with the abilities and power of full fledged legendary pokemon. William was one of these hybrids. Created form one of the lead scientists. Suton, the serperior, and his assistant, Lumiera the latias.The two of them never married, But Lumiera was deeply in love with Suton. doing anything he wanted for him. including being the biological mother for Suton's own personal hybrid offspring for the project.
unfortunately, The universe they lived in came under threat, and collapsed, leaving only William and a few others to survive. Lumiera herself was one of the casualties. But she was fortunately spared a fate of being lost to oblivion, as her spirit was captured by the poke goddess Máthair, and reincarnated into a new latias. Which became the latias that later sacrificed herself to save Amy as a child. resulting in Amy being turned into the latias anthromorph that William later becomes engaged with.
This lumiera seen above, is from an alternate timeline where, after the threat that destroyed William's original universe was stopped, all other timelines from that destroyed universe were restored, allowing other timelines to move forward without simply not existing. This lumiera, was left to care for William on her own as her son when Suton became dissatisfied with the results of the project, and moved onto other things. taking a new assistant, as Lumiera's constant fawning over him would distract him from his work.
This resulted in her taking out her anger onto her son, which she found she deeply regretted. and Wanted to make up for.
