Just a quick one: In the Inquisitor's Handbook under the Noble section, it does not show an entry for a sanctioned psyker under the list of allowable career paths, but in the random table at the end of the section it shows that a Noble can be randomly picked to be a Sanctioned Psyker. Is this a misprint, or intentional?

The fluff section are, I presume, just for fluff - to give hooks and ideas as to how various types of characters can be Nobleborn. I doubt their aim was to be extensive. The rules themselves seem to support the idea of a Nobleborn psyker, and really, if you wanted to, why not?

Our campaign has exactly one Nobleborn character and he's a psyker - Lord Baron Sigmund Hoyt Amos Castus the 13th, 18th in line of House Castus for the throne of Havenspire. He's quite a fun character so far, and now that he's Psy Level 3 has some half-way decent powers.
