I had a thought; Necromancers, especially Dwarves, may see their creations as an art form. If they do, they may try and create new works of art, similarly to experiments, but in a way more similar to crafting.
Thus, I came up with the idea of Necromasons. These are Necromancers with different behaviors than typical, run-of-the-mill necromancers. Instead of resurrecting corpses, they are dissected, with some organics stolen. Priority is given to Muscles and Brains. When what the necromancer desires is taken, they will either walk away or ressurect the materials they didn't want.
After this process, the Necromancer will take the materials gotten from their butchery and use it to create living tools and weapons. These tools and weapons are just made of flesh, or - if more than 25% of them is made up of brain matter - have a personality based off of whose brains it is. Here are a few categories of how these Object Personalities could be;
Mindless: These are loyal to the Necromason that crafted them. They will attack like any other undead if they are placed onto the ground.
Assistant: These are loyal to whoever holds them. If nobody does, they won't move.
Intelligent: If they are made up of more than 80% brain matter, they will hide behind doors to strike, be able to climb (if their biology allows it), and will - if a mouth is attached - be able to make weak, caveman-esque language.
Pissed: These are found discarded inside of the smaller buildings of necromancer towers, or on the plains around them. They seek to destroy literally anything, including other undead.
Like normal Dwarves, Necromasons make Artifacts sometimes. But they're not perfected flesh weapons, no.
When Necromasons enter a Strange Mood, they go on a rampage. They take a small group of undead and go on a massacre of any nearby towns or groups of fauna, quickly butchering corpses and taking what they need. After what can be weeks of collection, they hide away in their tower for days - if not weeks - until a new creature is born.
This is the Necromasons' Masterpiece, which is similar to an Undead Luitenant, crossed with a Giant, crossed with a Forgotten Beast. They are Semi-Megabeasts who are loyal to the Necromason, and will protect its creator at all costs. They are not capable of speech, and can come in many shapes, from formless blobs to towering humanoids. They all, however, are made of flesh, skin and bone.
Please tell me what you think of this idea!
