Necklace of Tongues
This necklace is crafted from a thin leather cord adorned with a variety of embalmed tongues. It grants the wearer the remarkable ability to speak any language of intelligent creatures. Quite the handy tool for a well-traveled Dragonborn like yourself, I'd reckon.
Now, as with many enchanted items, there's a bit of a... personality to it. The tongues, you see, come from each creature whose language you can now speak. There's a bit of unpredictability in the magic, though—sometimes things get a bit mixed up. Might find yourself saying something a tad off or misunderstood, if you catch my drift. But, overall, it's a powerful artifact for bridging communication gaps.
