- United League of Human Planets Codex on Foreign Species, Entry #30491: "Tall Men"
-- Species Designation: Hominem extrarius profundus
-- Other Names: Skinnies, Boogeymen
-- Appearance/Physiology: Tall Men are a large, thin species of indeterminate gender and lifespan, with no outwardly discernible facial features, extremely pale skin, low body masses and incredible height (average range of 9'-11'). Generally dress in very drab colors and wear masks when in public to conceal their (lack of) faces. Do not communicate orally; rather, they use their own form of sign language and limited telepathy. Come from a desert planet where the gravity is approximately 0.67 G, explaining their height. Species appears to possess limited psychic abilities, amongst them are: telekinesis, inducing hallucinations, levitation and limited mind control. Have a limited range of emotions that may not be as developed as the human one, but is fairly well developed.
--Culture: Technologically advanced, appear to be some sort of theocratic monarchy. Monotheistic, worship of a god referred to as "The Masked One"; their emperor is apparently part of a dynastic legacy supposedly started by this Masked One himself. Interesting, as it is unknown how Tall Men reproduce (they seem to be hermaphroditic).

Gender: Indeterminate, displays predominantly male characteristics.

Brief description of home world: Endless deserts punctuated occasionally by massive, incredibly advanced cities. Possess space travel capability as well as advanced weaponry.

History: Formerly a simple citizen of the Tall Men's homeworld, "Masky" one day found himself plucked from his daily business (who knows what that was) and dropped onto this nightmare plane.
