My character in the Forgotten Realms is an astronomer. Where in Faerun would you go to get *really good* glass made (lenses etc)? I’m currently thinking Neverwinter, but am open to recommendations. Tharsult, Schamedar in Calimshan, Luthcheq in Chessenta, and Tarmalune on Laerakond.
Superb lenses come from the East, too, but getting them unmarred in the Heartlands or Sword Coast is a problem.#Realmslore
