To start the day right one must fill the stomach.
Before heading downstairs, Iyas had been earnestly pleading with Yang Yu to teach her how to blend in like an ordinary person, how to avoid drawing attention. He was so clever, he must have a solution.
Yang Yu indicated that what she wanted was a peach to eat.
In terms of appearance, Iyas was exceptionally dazzling. Even if she weren't an elf, she'd still turn heads wherever she went.
The only way to avoid attention would be to either never see anyone again or to change her body completely, addressing the issue at its root.
After much thought, Yang Yu still gave the Race Disguise Necklace to Iyas, providing her some comfort. At least she could go downstairs and meet some people.
