The Warning.

Salvos didn't go back on his word. His eyes remained closed after he respawned. He snorted and turned away from Soverick. He felt disrespected that Soverick wouldn't relax even after he swore an oath. Swearing on your Origin is the harshest and strictest oath that you can swear. It is unbreakable. Breaking the oath will lead to the breaking of your Origin. 

It is so severe that Origin gods will die immediately and never resurrect if they break that kind of oath. Yet Soverick is still looking at him with calm wariness. He can see it in the child of the plane's posture that he can attack at the drop of a hat. 

He didn't say anything though. He promised not to antagonize Soverick so he will leave calmly with as much self-respect as a defeated man can muster. At least, now he can say that their fight had not officially ended and his defeat is not set in stone.
