The story happens because of the protagonist, not Palace Guard #2. I'm sure he's a great guy, and yes, he can be present in the story if he adds something, but I don't need his history and contact info.
To be a Necron is to be unutterably and incurably insane until the end of time, or, more likely, to be nothing at all, a machine that, only now and then, remembers how to regret.
