Now that they've got a tiny fragment of spellsilver out of the new kind of ore, what remains is a process of perfecting everything - not so much inventing it from scratch - and that in turn means that Keltham should maybe no longer be spending nearly all of his non-personal time on getting basic spellsilver running, as he has been these last few weeks.
It's time for him to shift relatively more of his effort into Law lectures, so that other people can force-multiply his efforts on perfecting the process they've found! Chemistry, physics, and Pilar-approved hopefully-safe epistemology for everyone. And the sort of stuff that even Pilar had trouble with, going in slower and more measured doses to the tier-2 mad-experimental volunteers (plus one cleric of Asmodeus).
