OBSCURE XENOS: BEWARE THE ALIEN | Warhammer 40k Lore

Xenos (pronounced ZEE-nahs or zehn-AHS) is a High Gothic term used by the people and adepta of the Imperium of Man that means “stranger“ and “alien.“ It is often used by the Adeptus Terra to signify enemy aliens or off-world, non-Human forces. The main starfaring, intelligent xenos species in the Milky Way Galaxy are the Drukhari, Aeldari, Necrons, Orks, T’au and Tyranids, though there are countless other intelligent alien species, most of them hostile, that Mankind has encountered over the long millennia of its expansion across the stars.
