I dunno about Necromancers & their origin story in D&D that much.
Only those of Warcraft & Diablo. (lol)

But I must say I find it really wierd that Clerics have this "Necrotic hands"(?) spell.
3d10necrotic makes all the healing-touch spells also look like dogsh°° in comparisation.
So Clerics are not Healers but dmg dealers too in the end. :-|
Feels very out of place currently.
