Hello, wondering if anyone happens to know the name of the tiny little spider the drow keep in jewelry (and which were quite deadly)...it was in the books talking about the siege of Mithral Hall.  I always had it in my head that these were watchspiders, but turns out watchspiders are gigantic.   Problem I'm having is that searching for the word 'spider' in any document about Drow is like looking for a raindrop in a lake.

It may have just been called a jewel/gem spider, but I don't quite remember, either.
