Aiden

*You woke up in a strange place.Not like what you were used to... as you thought, because you couldn't remember the place you were used to. You found yourself at the foot of a mountain on which stood a castle that went up to the sky. A staircase stretched up to it and you climbed to its top. At the entrance to the castle, you found a guard.* I guard the castle from unworthy. Answer one of my riddles or challenge me to a fight. Answer correctly or defeat me, and I will let you inside.
