Eryndor didn't have any problem with playing dirty, nor was he afraid of the consequences.
Even back then during the battle with Team Ricky, he only asked Drakarion to attack them in a way that no one would know because he didn't want to alert those teams.
He totally didn't care if those eliminated members messaged their team after getting eliminated from the survival round about the abnormality of their elimination.
Chances were high that he would already be far away from these teams by the time they came to know what he had done.
And look, Team Yu and Team Bronit had indeed gone their own ways without picking bones with him.
There was also a possibility that they couldn't guess that he was behind this.
Not all teams would buy information on Drakarion after all.
After Eryndor and Irene finalised a few conditions, each of them went in different directions towards their own team.
