The Big Four
"Who are they?" Nyx turned to her grandpa, eager to know what would make him react like this. Her grandfather was mostly a calm, easy-going person. There had only been two times Nyx had witnessed him being angry.
The encounter with Kron and Hendrix.
Nyx knew the reason for his anger then... but what was the reason this time?
Because everyone was speaking at the same time, it was very hard to make out who was speaking. She only heard a few people mention the term "Big Four" from time to time, but that was too vague.
After a while, the thick bloodlust that was emitted from Nathan gradually subsided, clarity returning to his eyes as he briefly glanced at his granddaughter and said in a tone filled with undisguised disdain:
"Those are the four most powerful noble families... they're also known as the four biggest scums." His face darkened as he added the last part in a lower tone, hate evident in his voice.
