What should've happened

Cover art is by: Neridiem; they can be found on tumblr(I don't know if they do commissions but they have very good art as you can see)

What if Gellert didn't mean to kill that student at dumstrang. What if during the duel between brothers the killing curse was thrown and Gellert actually saved Albus' life and accidentally killed Ariana. What if Albus wasn't an idiot and checked Gellerts' wand. What if they managed to peacefully merge muggles and wizards. What if they found Theseus in Paris after the duel with Aberforth and adopted him, later finding Newt being raised by hippogriffs when he was a baby and adopted him. Let's see how their story should've gone shall we?
