The dwarves are typically known for their rough style; asking them to develop heavy industries, engage in mining, and forge weapons poses no problem.
However, when it comes to finesse skills like purification and healing, they aren't particularly skilled. On the contrary, their arch-nemeses, the elves, especially wood elves, excel in this area, particularly in chaos purification and herbal potion crafting.
The Hesse Territory, due to the presence of mythical-level material Vocatrix's Scale and the extraordinary spirit plant Star Dew Sweet Orange, also has purification abilities that barely rival some wood elf clans.
Therefore, both parties signed an agreement: for every mine passage purified by humans, the dwarves will exempt the remittance of 120 elite dwarves for 10 years.
