=== The White Ships ===
Wherever the Emperor's arm reaches, there the White Ships of His Majesty's Secret Service will go. Palaces of the psychic arts, they provide budding psykers with a fundamental education or a vessel to carry them to more specialized training in the form of the many offices of the Scholastia Psykana. Such advanced training is on a strict volunteer only basis, but those who seek out the highest levels may be inducted into the ranks of the Secret Service or some other great agency and brotherhood of heroes. For others the White Ships provide a haven and a healing rest from the trials of life and service. Sanitariums as well as schools, the abundance of psykers aboard means that the White ships almost invariably take aboard the mentally ill for treatment. Time and telepaths combine to wipe away the stain of almost any trauma, and the wide variety of medicine available to the medicae aboard such a vessel makes them fully able to cure almost any malady.
