Ayda's 'damaged' eye is in fact not damaged but replaced with the eye of a daemon.
Ayda is the leader of TANAHOOO. She built this society together with Baltha Cadenza to keep or get things back under control. She was an adventurer many years ago and has lost an eye on her journeys, it got replaced by an artificial one that has a strange color and moves by itself. She is not telling much or nothing about her past, only the here and now and the possible future is in her focus. Ayda always can be found on board of The Artigo and she seems to never sleep.
