Group shot! A picture of the mane six on the maiden voyage of the S.S. Harmony in my Redblak universe. With the bearer of magic becoming ageless, it was suspected by everypony that they would need to seek out five new bearers by the time the others were in retirement with great grandchildren running around. However, it seemed that despite the Elements being returned to the tree of harmony, their connection still remained strong, and the ponies were not aging. Research and discovery lead to the knowledge that anypony associated with the bearers of harmony or were affected by them would live longer because of it… to the point of never aging past adulthood.
 
That and with Twilight being crowned princess of friendship, and Pinkie being friends with everypony she met… Well Pinkie had managed to drag just about everypony on the planet into this whole “live forever” thing.
