Well, I don't know which ones you have found, so I cannot tell you the exact location of the guard you need to find. Try going through all the doors you can. Keep in mind that you can stun purple guards with arrows so that you can go past them without them catching you. White guards cannot be stunned.

I hope that helps somewhat.

I don't remember i haven't played OoT since i was 4. I can't help u much. GL P.S. I think he is in the topmost point in the fortress or the place on the right side. (it's in a canyon or sumtin. neda stop typin hangnail is hurtin like hell jsut look aound.)

thanks

oky wen ur in the gerudo place (desert u c opening those r doors go thre them ir u get caught heres an easier way to get past them, just shoot them with ur arrows and it knocks them out for a long while, or use ur long shot wich stuns em for a few secs so go inside every dorr u can find in the fortress, if u got one alredy then keep going on 2 the next room and you'll eventually find em' the last one iz really hard to find but dont get discouraged, if i culd draw a map i wuld but then wut wuld be the pint in playing if we spoon fed u evrything
