Is it possible for someone to negotiate with the husband regarding the return of the treasure/schematics? Emet-Selch thinks the schematics would benefit his crew and the ancient relics would interest a lot of them too. I was thinking he'd be happy to return them to the widower so that Leroy's soul is put to rest but he would ask whether his crew can analyse the relics/make a copy of the schematics for their own use.
