|“|| Namarra, Long Sword +2
Also known as Neversleep, this ancient blade is thought to have been present at some of the most influential conflicts in Faerun's history. Sightings have been noted as far north as Thay and as south as the jungles of Chult, though documentation is oddly lacking regarding the details. It is perhaps a result of the sword's ability to silence all sound within a large radius, removing the effectiveness of attacking mages but also preventing any discussion that might have followed.
