Seeing this scene, Aiwass's eyes widened slightly.
When he saw the Elven Harp, the clues finally connected in Aiwass's mind into a single thread.
"...So that's what it was."
Aiwass muttered softly to himself.
In the original history, Yunus handled the matter of Anastasia on his own because he never managed to contact Sherlock.
Clearly, he botched the task in the end.
One piece of evidence was that when the players returned here following Yunus, they never saw Maxim and Lady Grace—the couple might have left, or perhaps they refused to open their door.
In any case, Yunus brought the players to a tree and told the tale of the "ghost girl" he had seen there, and showed them the "harp given to him by the ghost," hoping the players could check for any ghostly reactions. In the end, it was found that there were indeed no signs of Undead, and what he had seen might have just been illusions or hallucinations.
