Ohhh in addition to the "Adaines eyesight going from bad to worse from being the oracle", I always enjoyed the idea that the more she sees into the future the less she can actually see, ergo gradually going blind and the 'future sight' being the only way for her to see
I don't know, it's just macabre and ironic that the one who sees more than everyone else (-> the future) loses the ability to see the present
adaine blinking as she wakes up but she can't see her bedroom, instead she sees the future, death, sacrifice, destruction, triumph, joy, and rather than fading she after a few moments, it is all she can see. the futures fade into different visions, like constantly-shifting images. when people speak, she sees their futures.
aelwyn greets her in the morning and adaine only sees her sister when leviathan is raided, when aelwyn and ayda uncover locked rooms in the back of the library installed by one of ayda's past selves, when she and aelwyn hunt their mother down in sylvaire, when they watch their friends die and cry together, a thousand ways aelwyn might die--
adaine cries out in horror and covers her eyes as though she is seeing anything at all, but the visions sprawl out in her head, endless and horrible.
eventually, she begins to parse through them, begins to figure out how to control them. she can see what people might do seconds before they do it, can see all the different paths the world might take under her feet. but she will never see it in the present again
