Psykers are individuals in the Warhammer 40,000 universe who possess psychic abilities, allowing them to harness and manipulate the Warp, a parallel dimension of psychic energy. These abilities can range from telepathy and telekinesis to more powerful feats like summoning or controlling entities from the Warp. Psykers are often seen as both valuable assets and dangerous liabilities due to their unpredictable powers. In the Imperium of Man, psykers are closely monitored and often trained in specialized institutions known as Schola Psykana. While some serve the Emperor as Astropaths or Sanctioned Psykers, others may fall to the temptations of chaos, risking corruption and madness. Their existence is a double-edged sword, providing immense potential while posing significant threats.
