   Summary

   "I believe we'll see a satisfactory outcome eventually. Though if you are here to make a case for your Imperium, know that I will say no more tonight."

   Horus laughs, shaking his head. "No, Father can do his own negotiations, and I think he prefers it that way. I'm here to meet my new brother and discover what he's like with fewer eyes upon him."
