Currently, Sivan is going all out on dealing with Migron, the only reason Migron still had any hope left is that Sivan didn't reveal his full strength immediately and most of his troops are moving in stealth.
Sivan's style was never to move directly, he always worked in stealth and he always caught his targets when they least expected him.
Meanwhile back in the stray realm, Sam and Grivon wrapped up the drinking session. Even though this is the first proper victory they had, all they did is clean up the mess. That is all.
At this moment, Grivon is not the focus of anyone. Even the league of Blood Iron was fooled and they sent people in a different direction. In fact, in the past two months, someone came from the league and they focused on the scapegoat that Sam and Grivon created.
With the new and improved surveillance, they managed to identify the members that came and used Grivon's powerful subordinates to catch them.
