You marked them as canon in the CS. So I'm going by the canon quest dialogues (and ignoring the insanely remote possibility of talking godlike beings into handing you their artefacts for free), which entails doing numerous horrific things to get various objects of questionable utility. Hell, the Ebony Blade is specifically called out for driving you insane.
