Project Pandora

The "Artifact" is an unnamed enchanted object that was stated to be able to grant your heart's most impossible desire. Triad Industries referred to it as "Project Pandora". Cleo inspired Leonardo DaVinci to create the artifact and she imbued it with magic to seal away and shield her from Malivore until it could be opened by the one capable of killing Malivore;  Hope Mikaelson.
