that's really cool!
she's definitely found her niche, aha
...and i wrote a bunch of questions if you want to answer, but i think that they're mainly just the same question rephrased in different ways.
in your setting, if necromancy is just any death‑related magic, then is the focus of necromantic magic on death itself?
or is the focus still on the manipulation of life energy, just in more death‑y contexts?
i guess put another way, are the undead risen by necromancers in your setting animate due to moving life energy into dead things in artificial ways?
or are they animate due to manipulation of death itself?
so like, when elly necromances an undead to redead, is she just undoing its artificial life energy?
or is she undoing whatever is manipulating the undead's death?
or just something else altogether?
either way, i guess that they all seem pretty different from the typical cleric method of destroying undead with divine magic!
.......though, if your undead can be put to rest, does this imply that they still possess a soul or spirit??
i mean, i guess that this might be what distinguishes necromancy from like just animating empty corpses with some other magic (which, in some sense, would be like a false undeath — so false false life)
