Fezz listened to the duke talk about history and his plan, admittedly tapping out a bit mentally during the history lecture. He knew of the three ways, but the next bit was news to him.
The Blade's location wasn't too much of a shocker, ask a historian and you'd get many guesses (some rather absurd) as to where it was and the tomb of the king makes good sense. A judge well-versed in old law could probably tell you the last point about the law, as confusing as Empire law was, it is a point often made in insular courts.
No, the surprise was the location of the tomb. That was something kept in hushed secret, only select members with the knowledge to where even just knowing who knows is a grave secret. To put it all together.. He didn't know what to say at first, thinking about what duke Sepin had told him.
"...I don't much like the Empire. I don't much like the rebels either, after being forced to work with them for so long. The chance to instead choose a third option, much less one to also investigate and pick through an almost sacrilegious site of extreme historical significance to find an object of even greater significance."
"I'd probably of said yes on just the first point, but I'd be a really pitiful historian if I even thought about turning this offer down because of the latter." The scholar was practically trembling at the thought of it, his mind whirling about what might be found, actually finding and seeing the Blade, EVERYTHING! Good dragon he almost felt dizzy.
