SLO Art Challenge #6: The Artefact

[Nas]

Background:
(Inspired by another forum)
Forgotten to time, there exists an artifact of legend and myth. An artifact of great power. It is an ancient object imbued with magical properties that is sought after by adventures around the world. The new challenge for the next (2?) weeks is to design this an item or artifact.It can be any type and style you'd like even a weapon. Focus on a good sense of shape and silhouette to convey this artifact.

With the sudden pop up of 3D modellers I decided to make another challenge that also cater to them now I best see som 3D models.

Rules & Guidelines:
-This is a item design challenge.
-Approach this concept as if you were designing it for a in game rare/forbidden item.
-Any medium is allowed.
-WIPs can be posted in this thread and the final submissions can be posted in the "Finals" thread.
-This will be due in two weeks to give the modellers some more time so I better see some detailed work.
-Due the 16th April
