I'm currently running Keep on the Borderlands (ported to 3.5/PF1e, if it matters but I don 't think it will).

In the Chapel of Evil Chaos, there are four artifacts that turn anyone who touches them and fails a save chaotic evil. Thare are supposed to be a shallow bowl, 2 goblets and an ewer.

However, in developping a PC backstory, I've indrotuced a story arc with a noble looking for genealogy records, heirlooms, crests and other tapestries. My PC so far have recovered 2 of those for him, one even being a magical tapestry that can display anyone from a specific family and that can verify that someone pronouncing the proper command word belongs or not to the family.
I'd like to rework those artifacts to fit this idea. So that they can be of some importance in the local politics, mainly through genealogy and heraldry. I also want to keep the cursed aspect. I'm fine with turning a PC's alignement around (my players are aware we are playing old modules and these sort of things can happen), but I'm also open to other ideas.

Anyway thanks to anyone helping me out,
Have a great day or night and even greater games !
