Though you keep from showing it, you're quite surprised. The Chamberlain of the Seal answers directly to the Emperor and is responsible for foreign relations, and the current holder of the role is Graf Otto von Bitternach, who despite his youth has been able to cultivate a reputation for fair and straightforward dealing with the allies of the Empire. "What matters, specifically?"
"He would like your insight into the inner workings of our steadfast allies of the Karaz Ankor." Though the young man is clearly a bundle of nerves, you can't see any misdirection in him, so you give the only answer one can give when called upon by the Imperial Council - you accede. And as you follow the man into the part of the palace dedicated to the bureaucratic warrens that do their best to run the Empire, you consider what you will say. You owe loyalty to the Empire, but also to King Belegar, and there's likely to be questions put to you in the following meeting where your answer cannot fully serve both.
