Memory Stone

The Memory Stone is an Equestrian relic with the power to erase memories that first appears in Equestria Girls: Forgotten Friendship. Previously used by a sorcerer defeated by Clover the Clever, the Memory Stone was lost in Human Equestria where it was found and abused by Wallflower, a socially shunned human student at Canterlot High who first used it for small memory wipes until she uses it to get revenge against Sunset Shimmer for unintentionally wronging her by erasing the Humane Six's memories of her. After learning of the Stone in Equestria and learning she had three days to return the memories before they're gone forever, Wallflower is defeated after wiping Sunset's memory of her entire time in Human Equestria in aggravation and defeat, and she is befriended after the Humane Six destroy the Stone and get back their memories of Sunset.
