The dwarf skeletons were the main runesmiths in the project, while less experienced human skeletons acted as apprentices and assisted in the work.
Meanwhile, an increasing number of skeletons were developing magical organs within the army, thanks to search teams collecting magical herbs and rare plants farther and farther away.
The skeletons had discovered that the magical organ generated by any skeleton would serve as the base material for the fake core potion, not necessarily Athos's original organ. Therefore, the alchemist assistant was responsible for producing the potions.
Some search teams were unlucky and encountered monster stampedes, suffering significant losses, but it wasn't a major problem overall.
The biggest surprise, however, was when Simogo appeared in front of the castle a few days after the dwarves began working, carrying magical roots among his fangs.
