[There are probably necromancy rules about swearing on your own grave. But it's fine. She does a huffy sigh.]

I'll accept even though I did not find your oath convincing. Just. . . understand me. This poses a risk to my safety if used carelessly. I could trust Crux and Ortus both with this task, because whatever their personal feelings towards me, they valued their honour and could not betray their lady. I don't think honour has the same meaning to you.
