Context: The grayed-out portion of the image is similar to what a character's genitals upon turning into a Wraeththu are described as. If you don't know what this game is, I envy you.
But you don't understand! The Wraeththu are just better than us, so they know how to make things that look weak from the point of view of a dumb, inferior human, but they're actually even better than katanas, which we all know to be the pinnacle of human weaponsmithing!
