Acheri

An Acheri is a type of monster that can materialize their own form without the need for the use of a vessel, generally, if not always, taking the form of little girls.

History
When Leah was planing her coronation as the Source of All Evil she wanted to make sure the Destined Ones wouldn't show up to blow her plans, so she came up with the idea of sending an Acheri to keep them busy. As Chris and  Charlie were on a mission to help  Wyatt and  Prue, it was the responsibility of the other six of the Destined Ones to take the Acheri down. They tried to find information about this monster in the Book of Shadows, but it had nothing there, so Melinda and Damon went searching on Google and found that the monster they were dealing with was called an Acheri. They also found a way to vanquish the monster. They prepared a potion using which two of the ingredients were salt and melted iron and all of them tied a red ribbon around their necks.

Appearance
An Acheri can take the form of a human, especially the form of little girls, without using a vessel. It is unknown what their true appearance is.
