Ancient Greek divination rite where a passage to the underworld is opened and spirits are consulted for aid and knowledge via offerings, incantations, and supplication, famously mentioned in The Odyssey. Questions can be whatever you'd like but please keep in mind, this ritual does not call specific souls, only the ones closest to the underworlds opening.  This is not the same as mediumship, simply a strong divination method with departed souls.
