The Sword brought unusual power through manipulation of the evil side of the Essence, which is how Atrax maintained his dominance over his people: through physical might, essentially striking down any foe that opposed him among his administration.

The Crown represented a direct link The Ancients had into the thought process of King Atrax that the Ancients were able to manipulate.

The Golden Chalice was believed to bring everlasting life but was actually allowing the corruption of manipulating The Essence to enter the soul through the physical representation of drinking something.

These artifacts were originally housed in the vault of Fallow's Hold, which is one of the great dungeons of Ashes of Creation, located near the capital city of the ancient Toren empire, Torall. These artifacts were in close alignment to The Essence on Verra due to their proximity to the ley lines of Essence spread across the world. The four Ancient artifacts of Verra were originally discovered by King Atrax in his pursuit of the power of The Essence.

So there could be some relationship between these designs of the staves and/or weapons that you'll see, which are used to harness or focus the use of the Essence, or magic and how perhaps those structures relate to the types of magic that those creatures are using. Here in the curvature and design of this staff you'll see that it has a very specific and unique looking type of mold so-to-speak.

This is not the Staff of the Ancients per-se, it's a staff.
