Its so simple.......
Ask which ever one you want if "He sleeps with his brother?"
Of course the liar will say no and the truthful one will say yes because you already know their a bunch of faggots. You now know which way to go assuming that the truthful hermit lives on the side you want to go. But then again hermits scare me so i would probably turn around and go until i reached where i want to go, assuming that the world that you are on is bla bla bla i could babble like this for a while or just some it up right now.
Stay away from those hermits, because i have no other solutions and just got back from vacation and don't want to think so i will set my fingers on cruise and click the submit this thingy.
