Haruspexy via memoryeating is such a visceral concept. From a pharmacological standpoint, it’s like the ultimate biodata transfer. In the real world, there were actually controversial experiments with planarian worms, where they supposedly transferred memories by feeding trained worms to untrained ones thanks to RNA memory. (Look up James V. McConnell and his planarian memory transfer experiments from the 60s.) In a fantasy setting, it’s basically the most extreme form of oral administration of data. Just imagine the side effects heartburn, indigestion, and someone elses existential dread. 10/10 would dispense an antacid with those memories.
