Reiner (Lainah true form, the deity of existence itself)

Reiner Buddy (Also known as The suicidal great one, the suicidal above all; In other cultures known as Hel, Thanatos or Mors) is the true form of Lainah Blaun. It is not known what the origin behind this almighty but also non existent god is. He's everything but at the same time he's only another little fading object in the plain of this existence he created, the existence thats purely his existential crisis in a cruel and cryptic world, that he's not able to comprehend.
There is a legend that Reiner Buddy will take form and erase existence itself when the day comes that tyranny suppresses the people of Lainah Lando. In the end it is said Lainah Blaun will remember that he is the one, the one suicidal above all. In this moment he will turn to Reiner Buddy to erase the existence of this painful world and reverse time itself until the point where he's able to change the future... to create a better one. 
After this alternate time line is created Reiner will disappear from his existence, while patiently waiting to exist again (Which truly is paradoxical)
Everyone will lose their memories of the erased future and start again from the point to which Reiner Buddy reversed time. Lainah won't remember anything until the next time he calls Reiner Buddy, his true self, into existence
Reiner Buddy's last words were said to be: e^(iπ)+1=0
