Seth had vanished mysteriously and the only people who knew about it, were the Elf Queen, Rina and the girls from the Glazed Lake Sect. However, only the Elf Queen knew what he was currently doing.
Since she was occupied, telling everyone the details of what have happened, no one would be able to link the massacre that was happening on the Luberus Family mansion right now, to her. Like that, she would be able to maintain her image and the future safety of everyone.
After some time, Seth silently reappeared in the half destroyed Central Stadium and Arwen noticed his presence. He nodded towards her and she knew that everything was done.
"Ivasir! Bring the new unit under your command to arrest everyone from the Luberus Family. We must investigate how deep was their influence on everything that happened." She ordered it, making sure they would notice what happened there while she was still here.
