It's a very rare ore that conducts magical energy far better than steel or silver. You can't smelt it, but the Quey have ways of alloying it into their bronze weapons. We've found some promising deposits in the Cathnoquey archipelago, but we've only brought a small sample with us. Inge Coral-Crowned Disposition ≥ 30
It's a fascinating ore. Magic clings to it like no natural substance I've seen. You've helped advance my material science studies considerably, %PCName. Sergius Antellius
What a strange ore, indeed. You've done well bringing these to me. Take this fire opal as a token of my thanks. It's quite pretty, but offers little value to my studies. Sergius Antellius
Like I said, I'd bet the Nord ship Grey-Walker is carrying some bitterstone ore. If you bring me three, I'll give you something nice and shiny. Sergius Antellius
It's an incredibly rare ore in Tamriel. I heard that the Runners League found deposits on Cathnoquey, and I simply must get my hands on some for my research. I can't spare the expense on a faculty salary, but that Nord ship Grey-Walker just arrived in port, and I'd bet you they've got bitterstone on board. Surely a clever %PCRace like yourself could see that a few samples go missing? If you bring me three pieces of bitterstone ore, I'll give you something nice from my collection of fine gemstones.
