You know one thing has been bugging me since strikers and into vivid what if Jail never intended to destroy the TSAB at all of his plans including the creation of Vivio from Project F was towards one goal and one goal only the Restoration of the TRUE Balkan Emperor he only provoked Hayate's Team into action because he needed powerful guardians for Vivio he even went as far as provoke Nanoha in order to get her to destroy the Cradle
so it could never be used again which is most likely what killed Olvia so lets assume on the this theory that jail would at all cost assure Vivio's survival even if meant harming her in the process aka putting the relic inside her and forcing her to be the source of the cradle's power
the question of course is why go to such lengths to assure it? well let's take a view at jail's terms of thinking his not really a person his most likely a recreation of a specific person much like Fate, Eiro and Vivio but that person was unstable a radical genius who who was brilliant at out of the box thinking most likely one of Al Hazard's most brilliant men perhaps all of the events of Strikers was just one Giant Test to test Vivio as well as her would be Guardians
Now one might ask what would the restoration of Vivio mean? the Saint Kaiser is a Legendary Symbol on terms with the God Emperor of Mankind in Warhammer now think for a moment what such a Symbol with her full Saint Kaiser power behind her could accomplish
with all the Balka Tech and such resurfacing and her already existing Balkan Allies, Hayate who is at least part Reinforce in that she shares Reinforce I's Linker Core and Reinforce II is their uhm love child as well as her Love interest Einhart Stratos and many more
perhaps this will ultimately lead to the Restoration of Balka and Al Hazard
The only way these ideas will be incorporated (like the restoration of Belka and Al Hazard) is in fan fiction, since the creator of Nanoha seems to like to do bullshit nowadays.
That's why I'm trying to create my own story on it kinda (emphasis on the word TRYING, though, since It's coming slowly for now).
