You touch the disembodied brain of the corpse of any sentient being and instantly know details related to one specific person, place, or thing as the subject knew them in life. This applies only to information directly related to the particular subject at hand. For example, if the target is an aboleth’s brain and the subject is its lair, you could get directions to the lair and a list of contents inside the lair. However, it will not convey things about the lair that the aboleth did not know, or about any hazards along the way, or what the contents in the lair are used for. After the application of this spell, the brain melts away into useless goo. Access to the information gained through this spell fades from the caster’s mind after 24 hours.
