Per North Star’s latest email today, they have temporarily withdrawn some ranges because of staffing and raw material shortages resulting from the current pandemic situation. I don’t know if that applies to the Tanatus figures. You could drop Nick a pm here and I’m sure he’d let you know.
Someone pointed out the other day that the Thrilling Tales range had also disappeared from the Artizan pages in the North Star online store. I’m guessing the same thing applies.
