In Equestria everypony believed that the race of Changeling's died off age's ago. There was no evidence of there existence found after the discovery of the old hive found in the Equestrian desert's. Strangely enough no corpse's or skeleton's were found at the site either. It's all most that they packed up and left, at first ponies believed that they were just hiding …waiting till they let there guards down, but that changed after about 30 years when there was no evidence.

Well until one was found out side the town of Ponyville.
