Schematic of a Necron Tachyon Arrow: left is open and activated; right is closed and passive

A Tachyon Arrow is an intricate Necron wrist-mounted directed energy weapon worn by Necron royalty like Necron Overlords, Necron Lords and Necron Destroyer Lords. When activated, it transmutes a sliver of inert metal into an unstoppable thunderbolt capable of piercing the heart of a mountain. Such a weapon has near infinite range, and is able to penetrate almost any form of armour, including that of Titans. The only disadvantage to this astounding item is that its strange ammo supply is exhausted with a single shot, and is far too complex to be reloaded in the midst of combat.
