These people were from the nobles' factions that had always opposed the royal family.
In other words…they're enemies.
Jake was close to the people from the royal faction.
It's natural for him to know the infighting among elves and the factions that he had to avoid.
He just didn't expect a group of elves from the noble's faction would suddenly barge into his mansion.
Maybe they had killed the guards outside or simply knocked them unconscious.
These elves couldn't be taken lightly!
Hearing Jake's words in elves' language, the leader of the group obviously realized that Jake wanted to trap him.
If he was still arrogant, Jake could bring this matter into a dispute between two races.
He wasn't worthy and didn't have any authority to be involved in such a serious matter.
