Constance is from a village where things are a little different.The apples there grow white, and hold a secret.Every little apple tree in the orchard is linked to the soul of a pony in his village, and thus, a benevolent soul will make the apples sweet and savory.But any malicious or ill intended action will cause the tree to produce bitter tasting fruits for the year.Why do they do this? A calamity befell the area a thousand years beforehand, and a large burst of magical energy was produced to counter it's track of destruction.In the immediate location of where the burst took place, all of the trees and wildlife were irradiated by the magic and slowly took on a new form. The apples turned white, and the fish in the ponds nearby began to glow in the dark.Brightly colored Will-o-Wisps also appeared shortly after, with a playful personality to them. They say it's the Will-o-Wisps that watch the ponies and make the apples bitter if they do anything ill towards another.As time went on, some earth ponies found the trees and all the other fascinations and settled in treehouses built in the surrounding forests. They lived rather isolated lives, and were rather xenophobic and afraid of outsiders.Fast forward back to present time, and we have Constance here with Applejack. Showing her the White Orchard and allowing her to partake in the fruits. The tree with his cutie mark on it is the most bountiful tree, and it's fruits are said to be the sweetest.Kinda like Constance is himself.Art is byHe does amazing work, I would recommend watching him.
