Are you sure you were standing next to Ordos and not an Ordon Priest or something?
Ordos is on the balcony up the steps in the north of the centre courtyard (square) area on that plateau. He has no mobs by him. The half circle area to the west (where the Blazing Chest is found), the lake/gy to the east, and the whole area around the outside of the walls should be fine for people without the cloak. It should only be within the square sanctuary in the middle that the pulse goes out, as soon as you move in the front gate.
Might be, because this one clearly changed position. I could not care less for the guy, so was probably too busy being worried I'd get ported out to actually see properly what it said. I was just after the chest.
I often fly as high as possible in the fatigue zone behind the ruby lake, and then go forward pointing to the ruby lake. I usually land right into the lake where Garnia is. From there you can just jump down into the sanctuary. It takes me only a couple of minutes to get to Garnia this way, so I imagine you could also get to the sanctuary easily this way.
