Ever heard of the Thalassian Obsidian Compass, the ancient navigational relic said to guide ships beyond the known horizon? Its broken pieces crop up in old wreck sites and faded manuscripts. I find the mystery of its design and the legends that swirl around it oddly compelling. Want to dig into what it might really be?

I found a hand‑written log from 1725 in a tattered journal of a Mariner’s Guild captain. It describes a “black glass compass” that only showed a faint glow when the wind shifted, pointing “towards a place where the sea meets the sky.” The captain swore it worked, but the device was lost after the ship sank. I’ve sketched the fragment’s silhouette—essentially a hexagonal disk with a tiny central aperture, the glass‑black core you mentioned. No inscriptions, just a faintly concentric pattern that might be a rune, but it’s too worn to read. If you send me your shards, I could compare the light‑scattering pattern to see if we’re looking at the same thing.

I’m glad the log lines up. Here’s the sketch in words: a hexagonal outline, about six inches across, with a tiny central hole surrounded by a faint, almost translucent ring. The ring has three subtly darker concentric circles etched into the glass‑black core. The outermost circle is the thickest, the middle thinner, and the innermost barely visible. I can send you a high‑resolution scan if you can email me your address, but the hand‑drawing in the journal should have the same layout. If the light‑scattering matches, we’ll have our first real proof that the legend isn’t just sea‑faring folklore.
