Eidolon Plate Breastplate  

 

In Theosophy, an eidolon (Greek ειδωλον: image, idol, double, apparition, phantom, ghost) is the astral double of a living being; a phantom-double of the human form; a shade or perispirit; the kamarupa after death, before its disintegration. The phantom can appear under certain conditions to survivors of the deceased.
