Wanted to write some things concerning necromancy (and animancy) in my world
First off in my world souls are just tightly wound magic shaped by the living things life. Every living thing has a soul but things like plants and insects have weak easily bipassed souls while fae and dragons have powerful almost unbeatable souls.
Second a living soul is very hard to bypass or affect while a dead soul is much easier. Plants and weaker animals can easily be charmed and controlled, animals larger than say a rat put up more resistance, mortals require a lot of power or skill to control and greater creatures are a legendary feat
Thirdly dead souls are the pattern left behind after a thing has died. Only mortals and occasionally animals leave behind remnants. Dead souls cannot learn or change as they are only the left behind memory of the living
Finally as souls are magic they can be controlled by the magically gifted or educated. As previously stated a living soul is hard to be manipulated by an outside source but a dead soul or your own soul can be manipulated much more easily. Those who manipulate souls are animancers and those that specifically work in dead souls or in animating remains are necromancers
