This is an updated version of this: [link]
It's the Double Bow and Arrow brand of the Goddess Artemis as portrayed in the Dark-Hunter novel series by Sherrilyn Kenyon.[link]
All Dark-Hunters (Except Zarek of Mosia) carry a black symbol like this (minus the ring) carry as long as they are in service to the Goddess.
This version of the animation uses a proper gold metal material, better bow and arrow models better lighting, and a black-red-black gradient as a background, similar to the one that adorns the Hard-cover of the Dark-Hunter Companion.
DISCLAIMER: I own nothing except the software I used to create this (3ds max 8 and Photoshop/image ready). The Dark-Hunters, the Dark-Hunter symbol, and all associated characters and places are all (C) to Sherrilyn Kenyon.
