Alcides third Noblephantasm Theories the Background of Reincarnation Pandora

Greetings fellow Fate Fans !

Honestly since i did read in the Wiki about it did i foundi t a realy intresting but to am wondering its a great Enigma for me ? as i i dont have any idea how Herakless could have it otherwise that he get it through his coruption as sort of effect of the Angra Mainiyu mud that some characteristics were heavily altered as for me Herakless is the crossing over boundaries over his own and human borders that just after he refused his own Apotheosis his limitbreaking did it resulted in a Archievement stealing Np that breaks the crystalization of a other ?

thats the only theory .i have i would be curious on your all Thoeries ,thougths and speculations about its origins and backgrounds !?
