This guy is like the gate keeper in front of the shrine i think w/ the glass door and a lock. He asks you questions, what feels hot but isn't fire, something like that. Anyways anser is ice. He asked me another question, about protector or keeper, not really sure. I answered wrong so he attacted me. What is the correct answer? Is there even one?
I decided to fight him, but he turned all my characters insane almost instantly. There was nothing i could do

What do i do, or what is he good for?
