"Haash. Finally absolved of all involvement."
Eren said after he was done cleaning his most recent crime scene. He knew the kingdom of Edinburgh would try to find the culprit who had eradicated the vestige of Sage Nira's soul.
Thankfully, he had the infiltrators of Layos to blame things on. The first thing he did was get rid of his presence as much as he could. Then he decorated the crime scene with fake evidence, scattering the mangled body pieces of elf infiltrators all around inside the hall.
Of course, Eren didn't have to erase his presence from the scene completely-- just make it much less apparent than it was. After all, he was one of the participants in the Sansara array who had entered the Sage's Castle to claim Nira's legacy. So it was fine for his presence to be registered here like the rest of the participants who had appeared here with him before Nira sent them on a wild goose chase.
