Merovac's Amulet

Ithaqua_medallion.jpg
A medallion made from an unknown metal, carved with strange symbols that match no known language or system of symbology.

It was first described in The Devil’s Simulare, but vanished after the 1204 AD sack of Constantinople. The book mentions it being brought to the city by the treacherous monk Merovac and used in a ritual to call some angelic power from the heavens, though the details of this were excised from the book at some point.
