Norn aren't humans, but they certainly seem to have human-like attitudes towards desecrating the dead. No, you still humanising norn way to much, don't tink about them as u think as human or real world human culture paralel, there is nothing in lore that suggests that the Norn view necromancy badly, in fact what is known is that the Norn will use whatever seems cool to destroy their enemies, I don't see why a Norn would see bad the practice since they think beating a drake to death with its own child is cool AF. And this you see as soon as you start with your character norn, just as you see that the norn use firearms, which gives them a good place as engineers, many Aetherblades are norn. Being an engineer does not imply being a genius in mechanics, but having it as your fighting force. Even the engineer as a playable profession is based on the use of weapons instead of inventing things, turrets deploy them, do not create them at the moment, the engineer is never said to create his kits or weapons, only knowledge is needed basic powder and maintenance just like any other weapon. Norn cannot be seen as technologically retarded, he simply does not need it, he has magic and an absurdly strong body and it is said in lore that a single norn can against a small warband who still a very powerfull forse, when a norn uses technology they go for the big nuke kinda like Champion First Mate Horrik he uses a fucking cannon from a fucking airship, also all norn gun design are fucking huge.
