(OOC: When Martin sees the necklace, he memorises it so that he can use it as a Scrying target later. He also checks to see if he knows anything about it--Knowledges are at least +7 (+11 for remembering things) and at most for Arcane stuff +20 (+24 for remembering things), with a lot of intermediate numbers for Theology/Philosophy, History, Pop Culture, etc )
