The fae don't realy hate us, but see us as lesser creatures. Play things. Fae are vastly more inteligent but still are very child like in nature. Imagine the worst tempere three year old, now imagine it with near god like powers. The ointment for your eyes allows you to see the fairy folks. You can use it to initiate a meeting with them. A faerie circle can be any size. They can naturally occur to occupy up to about 4 humans. They arent good or evil. Just insanely emotional.
