oh as for suians apartments, you have to consider techniquely swords are practical for three reasons, theifs and brigands have breeched the tower during the trolloc wars dark friends also invaded, and dragon friends have also breeched the walls i guess, so that means theirs wars that breeched the twoer, fine reasons for weapons even in private chambers especially with channelers about that could betray people, or detect channeling, which is a interesting point,
more so suian being suian, if someone were in her rooms and she wanted to kill them, she needs them to threaten her life with a sword or something very frightening so why not let them have something to pick up and attempt to kill her with even though they would likely be more intent on escaping, then she can just burn them to dust or ash or whatever maybe freeze them and then send them out the window
