One central group of artifacts of Diablo is the soul stones, in which the Grand Evils' souls are imprisoned to keep them from reincarnating in Hell.
In the Elder Scrolls universe (the earliest I know is Morrowind), there are also soul gems which trap souls, but they are much more common, being used to enchant items and recharge enchanted items.
Common to these two is the theme of a stone that is used to trap a soul without the victims consent. In that they are different to, for example, a Lich's phylactery in D&D.
Do these two share a common origin? Did Diablo influence TES here? What is the origin of "stone/crystal used to trap a soul"?
