She is my favorite of the minis so far. I just saw Kingdom Death and it was a huge letdown, that everything, absolutly everything was out of stock. Today finally some figures got a restock, unfortunatly not Koshka the White Speaker buuut Twilight Knight, one of my other favorites and I didn't hasitate buying her. I hope Koshka gets a restock too, so I can get her.
I cant tell you who is doing the casting, but maybe Adam will, feel free to contact him at the kingdom death site in the link! The first exclusive batch of 100 mini's was sold out pretty much straight away! Im not sure when the next run will come available! But if you want to jump onto the mailing list do so, that way youll catch the releases as soon as they are available, and youll automatically get first dibs!
