I wouldn't make it habit to reward a PC for holding back on his employer. I must assume that, since the schema are the whole point of Elaydren sending the PC's out on adventures to begin with, that the House Cannith want the schema pretty badly. So does the Lord of Blades, though he isn't inclined to be as nice about it. After a while, House Cannith should learn of the gnome's deed, and when they do, they won't be happy either. The PC's have made enough enemies that they don't need their potential future employers as enemies too!
