So I am Aware of the End of the MLP Series (Just Generation 4) and Since I saw a Couple of Heart felt and Emotional MLP Deaths of the Mane 6 In Particular “Twilight’s Friends”.
 
 
And Where not sure how the series is going to end And Fans might make up their own Theory and I know you guys would make up your own theory in the Comments.
 
So I thought I do my Own theory that Grogar and his Villain Squad Killed Twilight’s Friend in say “A war” and twilight’s Re-form friends Back her up From Trixie, Sunset Shimmer, Starlight Glimmer and Tempest Shadow. Together they Destroyed the Villains and Now witnessing their Fallen friends Death they Buried them and they all fall in Tears.
