You got one shame and managed to stop anyone else from finding that proof of your shame. That woulda been an absolute disaster.
There's a difference between "behold. Our ancient lost art restored." And someone going "look! They worked with Elgi on runecraft!!!
So that's it, end of the line for the research chain into our most emblematic artifact, the one that is in our character's name?
Bah, that is probably worth extra shame for the cowardice.
Seriously though it is a bit of an anticlimax.
