Future AU Viktor and the Rune symbols

This AU Viktor has gone through something different and chose a different path,he probably won the war and achieved this “Perfect Future” which turns out to be just ‘Dreamless Solitude’ so this Viktor is able to travel through different timelines without the drawback of losing his power or life overusing his arcane magic, He goes on to these different timelines to save them from their Viktor from causing this disaster of a future.

Can someone help he understand,

-How did this AU Viktor achieve this perfect future without even transforming to his Glorious evolution form ? Bro is still mostly Human

-Did he create his own time loop paradox by going to the past in his own Timeline and Save Jayce so he can get this exact Future

-He saves Jayce from different timelines because he’s the only one that can show their Viktor his own creation lead to, but why even give him the crystal rune to invent Hextech ? If no Hextech no Mage Viktor no ?

-Does he just stay there and show every Jayce this Future so that they can stop the Viktor’s of their own timeline ?

-Finally the Rune SYMBOLS, why is the symbol of the rune different in every other universe ? What is the significance of a particular symbol that he gives kid Jayce or did every other symbol fail and this was the only one that worked ?
