Well, it seems that quite accidentally I and Egin have triggered a discussion.
Egin, yes that does make sense though the story is based on a number of assumptions that are rather improbable though not impossible (finding the charm in an abandoned house, the occupation of one of Velrats ancestors etc.)
DAD, your idea of rings with inserted Charmine Stones is interesting, yet in my opinion such rings should be VERY rare, as the "learning ring" is a complex item and requires much skill and knowledge to craft.
And as for the rest of you gentlemen I bow, applaud, and will listen to anything else you have to say, it is quite interesting.
