A interesting gal, although her kookiness may make her a bit too "odd" for some groups to take seriously enough and her excessively reclusive nature and unwillingness to interact with anyone make working her into an adventure in a worthwhile and useful way very difficult.
Some extra info on why she's so "odd" (not having a lot of /any friends doesn't really make one Kooky, more lonely and self reliant hermit) would be a nice addition,.
Also, there were a couple area I found her unnecessarily difficult to use in a game:
If players get into a conversation with Myna, she will deliberately act bored or busy to avoid being there for much longer. She may even enchant an item and give it to the players to get them to go away.
If this is how she reacts to people why would any players interact with her long enough to make a difference/be a useful reoccurring addition to the adventure? It also would be a poor quality for anyone in the vendoring business, since it would quickly drive away customers. (assuming gms want to use her as more then a one shot encounter the players are seeking for reason x or minor magic vendor )
Perhaps changing this bit to reflect she acts bored and busy to get rid of those she finds unworthy of her knowledge and not their to make a purchase and otherweise uninteresting would work better. (All mages seek knowledge so she would perhaps be friendly to a fellow magic user or scholar for info if nothing else)
She has never taken on an apprentice nor does she share her knowledge with others.
With this being the case what benefit will she offer any group that does seek her out and tolerate her "bored/busy act" to try and get info/item etc.. out of her? (It would make interacting with her successfully extremely difficult unless the player/s "pulled rank" and coerce her through magical compulsion or threat of bodily harm to cooperate with their needs)
Perhaps changing this bit to be never freely sharing her knowledge with others she does not deem worthy would help. This would help spark potential plot hooks and favors as the group would need to go to some actual effort to gin her favor and learn whatever bit of magic or info they were after.
Changing these character areas as well as adding some plot hooks detailing how a group may wind up interacting with her would make this a much more useful and enjoyable submission. As it stands, she's got potential use, but is too cut off from everyone/everything else to be a useful npc for most campaigns.
Additional thought:: Assuming familiars are normal among mages, why doesn't she have one, or if she does, what is it and what is the nature of her relationship with the familiar?
