yeah, you have to beat the other karanahn princes till you get to him. it will take a while, so bring friends and potions. also, it's the key not the cipher, and even if it was a cipher it would only be the third one. the fourth cipher is nonexistent. and by the way, he wasnt telling you to go to the storm temple, he was telling you to go to karanahn palace beyond the barracks. you should listen more carefully next time.
