i wonder if his blindness is psychosomatic meaning that mental stress is so great that it causes physical affects on your body. it is real even though it is technically only in the subconscious. there are multiple cases of people going blind for no physical reason but it was purely mental stress. i wonder if that would be it especially if he had a truamatic past and also had to deal with assasination attempts all the time. the only reason i think this is because i don't know if i a liquid could do that without causing any physical signs like an acid attack might? (assuming it isn't a fantasy world which it may be super low fantasy)
