Princess Almeyda Invictus, latent Goddess of Dreams, daughter of the Stars and Moon.
 
Ditzy and somewhat scatterbrained, yet highly intelligent and driven she needs to be, Almeyda is a curious and fun-loving filly surrounded by the adoration of relatives - both by blood and honourary. Twilight and Rarity’s affection for their little dreamer rivalled only by that of Wheatley, who was positively ecstatic upon learning that he was going to become a grandfather.
 
Hair gradients and glittering at this stage isn’t from her or her mothers’ positions as alicorns, but rather as natural traits passed down from Rarity’s crystal pony ancestry.
 

 
This is a concept for a not completely canon RariTwi girl that has been in the works for over a year now, with colours/design/personality/etc subject to change.
