I'm going out on a limb here, but I'm assuming that Percia, you know, Fate's mother, had found a romantic interest at some point in her life, and thus Alicia was born, a normal humanoid girl, but obviously with some sort of magical potential, right?  I mean Fate has magical potential and is a biological copy of Alicia, so I'm just connecting dots here.

So that got me to wondering, who was he?  We know that Percia's personality dramatically changed when she lost Alicia in whatever accident happened.  Why didn't he stick around to help raise this little girl?  Was he one of those deadbeat dad kinda guys who disappear whenever his beloved becomes pregnant?  Or was it something more tragic that occurred, like a different accident?  Boy, that would really turn somebody down the psychopathic road, wouldn't it.  First your boyfriend / husband, then your daughter, the only living reminder of your beloved still left in your life, both die, and are snatched away from your loving embrace?

Did he leave maybe for another reason, like a lack of love on Percia's part?  We know that Percia was deeply committed to her work, and maybe she was so obsessed with it that she ignored her romantic partner, so he left.  Or did that happen because he left her, and so she became a workaholic, as a coping mechanism?

And this leads to probably the ultimate question:  If he had remained by Percia's side, that means that Alicia wouldn't have died in the first place, thus preventing the creation of Project FATE at all, and of course, then Fate wouldn't have been born, and then she wouldn't have been on a mission to find the Jewel Seeds, nor would she have met Nanoha, and now the entire story has just become unraveled!  Great job!
