Unchecked and untreated Light corruption running rampant in U'nia's body for so long led to her losing her sight fully in her 30s. Luckily, she has a wonderful support network in her friends and partners, and re-accustomed well.
She can still 'see', if you can call it as much. She implores Aethersight like Y'shtola, but significantly less often. She ops to use her Soul Sight more than not, solely to keep track of people that enter or exit rooms, or to more or less look at who she's speaking to. Due to only seeing souls, it doesn't pick up on any inanimate object or other soulless entities. It's significantly less draining to use, however.
When on her own, she implores the aid of her seeing eye carbuncle, but her daughter Vivienne is always more than willing to accompany when she's home.
Also bonus shot of her cane! It sends an aetherial pulse into her palm when it detects a change in elevation (made for her by her friend A'vyra):
Rain in Thanalan is a rare thing. While A’vi complained, Rael smiled. The rain meant life and Rael could almost hear the plants and animals sing in joy about the precious water. How much more alive this land would look once the dark clouds had passed.
