Those clothes were forced onto her by Alyssa, and every different piece of the outfit came from a different Asur slave, who was ritually tortured to death, and were being used as dead mannequins for a makeshift shopping/clothing try-on montage for just the two of them. Every single thread of every single piece of it, every fragment of metal, every patch of leather, was made clean and purified of the rotten, browned, clotted gore that had covered it, while the very souls of those who had once worn them were magically interwoven between the physical spaces of the threads on a layer to form a quiet but consistent chorus.
Of eternally agonized screaming.
Just on the far end of hearing, not loud enough to really be a distraction, not really. But never going away. Ever. In fact, you could learn to live with it quite easily. Like how some people can go to sleep to the rain, or white noise from a fan.
But the wearer would know. Would know that those screams on that distant edge, almost imperceptible but not quite, are of pained innocent elven souls.
Sadrina made the executive decision that wearing them was not something she'd continue to be doing, and instead salvaged up Druchii armor and shielding and weaponry instead, because at least that was made with open honest cold craftsmanship befitting Druchii rather than what Alyssa had so 'kindly' made for her.
The plan is for this knowledge to be revealed in-update, as well.
