Horrid, disturbing creatures, the eaters of knowledge are the agents of Ilsensine in the greater Outlands and the planes beyond, handling those tasks for which the god-brain does not require the stealth ofcranium rats or the will of the illithid; entering places where Ilsensine cannot otherwise extend its awareness, and collecting knowledge either through observation, or by harvesting and incorporating the brains of others into its form. At times, they are even sent against the illithid themselves, serving as living weapons against any that may have displeased Ilsensine.
