Astropaths are specialized individuals in the Warhammer 40,000 universe who possess psychic abilities that allow them to communicate over vast distances in space. They serve as vital links for interstellar travel, enabling ships to navigate the dangerous and chaotic realms of the Warp, a parallel dimension used for faster-than-light travel. Their powers are essential for maintaining communication between distant planets and fleets. Due to the risks associated with their abilities, astropaths undergo rigorous training and often face significant physical and mental challenges. They are typically employed by the Imperium of Man, where their skills are crucial for coordinating military operations and ensuring the safety of space travel.
