Shyvana's father's personality was completely different from what all of them thought. It made sense why the other vampire families saw the Coldharbour family as weak. Still, at least he was decent, which was what most people should aim for.
"So instead of dwarves, you brought lizardmen? That is even better for the task we have in our hands." Hephas said.
The ore they needed to excavate was called Azularite, which existed only underwater, making its excavation a pain in the ass. Hephas wanted that ore because of its properties, which allowed him to manufacture weapons, and armor for his soldiers.
It was a magical ore, so its durability and sharpness were on a different level, not only that, but it ranked among the top best ores!
That reason alone made Arthur understand why count Hephas was so eager to get his hands on those ores and why he was willing to pay an absurd amount for the lizardmen to excavate them.
