Soulprison

Soulprisoning is the horrific act of permanently trapping a person's soul within an object—usually a tree—within the ethereal dimension of Ambarhal. This is achieved by combining soulsundering magic with the physical death of the victim. Elanil discovers the terrible mechanics of this magic when she finds her mother, Melenora, trapped within the "latticework of cells" of a Tree, forming a literal "soulprison". The ancient scientist Orym (as Aten) famously utilized this technique to imprison the alien Twins inside a cypress and a willow tree, trapping their souls to siphon the power of the Xyclami device.
