The Bone Smiths
People are always surprised when they find out that Saminga actually has quite a few competent artificers working for him. They probably shouldn't be: necromancy is Death's major operational priority as an organization, so it's not unreasonable to expect them to be good at it. That implies a certain institutional knowledge and acceptance of Enchantment among Samingans. As necromancy is not the only thing that uses the Enchantment skill, it follows then that various Servitors of Death would have branched out into other fields of artifact creation.
In their own particular way.
