We all know the father of Crota and boss of the new expansion TTK, Oryx. Look at how Oryx is spelled backwards: Xyro Seem familiar? Well, if you remove the y and o you get : X_r_ See what it's starting to look like? Now, take y and o and put them together: yo But it's missing a letter, u. Now, add you to both words, you get: Xur and you In other words, Oryx is you and Xur combined, from another, backwards dimension, an inverse dimension. The Taken are shadows of what happens when Oryx (you and Xur) tries to take beings to his (their) dimension. Oryx isn't evil, he's two lonely people stuck in one body. On an entirely unrelated not, none of this is real, I made it all up out of boredom.
