And this slide is about how parents would love to see their child again

I always wanted to play a traveling salesman who offers discount ressurections and speaking to people's loved ones, but really is just a necromancer. Really sleeze it up, you know?

Edit: "Why are you an adventurer?"

looks behind themselves to a trail of pissed off villages

"For the new opportunities of course!"

Literally the Dusties in Sigil. They're basically just necromancers who are also lawyers and loan sharks. They have contracts for their zombies. You sell your body when you're alive, they pay you, you eventually die and now you're a janitor at the local tavern for all eternity. They might even use those dudes who talk in rebuses as a PowerPoint to make the sale.

Most op strat is rimworld is to reanimate the corpses outside your walls. Then in the middle of the battle reanime all the new and old corpses again.

I think you just described organ and tissue donation in the context of the military industrial complex.

It’s the virtuous necronomic cycle.

Adventurers contribute corpses, are raised by necromancers, require adventurers.

Necromancy gone wrong

NPC: My poor husband and child. They were murdered by a group of orcs. Will you help me get revenge?

Britt (the Necromancer): Accept.

Later, at the orc camp.

NPC: My child! My family!

Britt (the Necromancer): Yea, I thought I'd bring them along for the revenge mission.

I've actually got a setting/ system that uses this idea as a world building start. Necrobiotic by Penny for a Tale. It's pretty cool, although i use it as a guide for world creation with DnD games rather then playing in the created system.
