The original design of a weapon that was found on a frozen, dead world in one of Ark's forays beyond the Ether Gate. The weapon sports several small, purple jewel-like orbs inset along the hilt guard and secondary grip. When tested to aspected ether exposure, these gems were quick to take on that same energy, and disseminating it throughout the blade.
Engineers speculate these gems were designed for this purpose, to give this weapon aspected damage to exploit a foe's weaknesses.
(This physical design is retired and is no longer canonical.)
