The dwarves had made many golems. They had also begun working with the angels. This had brought the idea to create these unique golems that mimicked the angel's thought process when it came to studying manas.
This was because the angels would normally have their own focuses on research. Those that focused on individual elemental manas while others looked outside. Thai piqued a lot of interest when it came to the dwarves who had been working on golems that the spirit race could control.
The simple idea that all three races working together could make unique golems was not new. Just as the wandering blacksmith had been involved in some, if not all, the theories associated with this while the party was focusing on themselves.
