To be honest, becoming the first vassal family of his Darknar family was not necessarily a good thing as using the former demon king's name was still considered a taboo accross the demon continent. So any family that decided to attach themselves to that name may be branded an outcast.
The chances of other families attacking them to get to at Tyler were very high and failing to protect one's vassals would be a blight at his qualities to use the Darknar name.
Such a thing was enough to turn the entire continent against him. However, it didn't seem like the Hervia family cared about such a thing as Anox hadn't even hesitated in utilizing his authority as the Hervia family's representative to immediately become Tyler's vassal family the moment he laid eyes on him.
Naturally, this had made Tyler a little bit curious as he hadn't expected such a sudden turn of events given how the other representatives had acted.
