Tyaethe
Taking a few deep, and completely unnecessary from a biological standpoint, breaths, Tyaethe closed her eyes and let one sigh out before going back to the more-appropriate language. Right, paladin and everyone's senior, that had its own standards of expectation.
"Right... items that completely bypass willpower like that can't be of mortal make," the vampire stated, holding hope one hand the instant it looked like someone would intervene, "Not aren't, they can't. You could overpower an entire fort in the right situation, but that takes an enormous amount of magical power. You could make an item that would do it to one person, have it puppet them, drain them of mana, and repeat, but not something like..."
She wandered forward a little, then pushed apart two bodies slightly with a foot, "This, where two people were tearing each other apart and a third one got stabbed in the back. You just... can't put enough power to do that into a static item, not without a high chance of someone breaking free. Especially when you make them attack their friends."
The paladin returned to stand by the rest of the group, frown returning, "And the things that can do this... I've seen them before. Maglad gathered them up, relics from Hidroroth's attempt to subjugate the world. Items woven into the fabric of creation only to dominate. Even without their creator, just touching one would make someone into a puppet, and with the proper mechanisms, anyone could take control. This is... better. But also worse."
At least the similarity explained her reaction.
"That 'shard of glass' sounds like a piece of Angroron. It was a sword once, or something shaped like a sword. It's..." Tyaethe cocked her head, hair trailing on the ground, "It's hard to tell how much is poetry and how much was a description. The name passed down through Talderian is..." and that, while definitely familiar, was even more archaic than usual, "Something like 'The Hole in the Tapestry'. The Elves called it the Wound of the West. It's probably as close as something can be to destruction made manifest, some thing from the time of the Veil's creation that Orodrunn repurposed. The full sword would instantly kill you on a touch, this... well, I guess you try to kill everything else instead. I don't know how it affected everyone, but any amount of magic and sacrifice would interact horribly with this."
Looking up at the evening sky, she added, "Short version? We're looking for part of a thing that kills on a touch. If you find it, don't touch. And unless you're working for the King, Sharky, I will not let you take this back to your employer." Regardless of what the other knights might think on this. The Church was supposed to have these locked away, that anyone had stolen one...
