Guard Shilster is normally found at 1366, -2747, in the north east corner of the zone. I was giving this guy mountains of gold when he decided to wander off, so I followed him. He cut a perfectly straight, diagonal line from where he was standing all the way to the bridge to the Southern Plains of Karana on the south side of the zone, stopping at roughly -3979.45, 1207.08, -18.69. He stood there in the road for all of a minute or two, and then went straight back through the zone on the exact same path, in the direction of where he was previously. He almost reached it but then seemed to despawn, so I hurried over to 'his spot' and found him there, freshly spawned. So, if you're looking for him but he's not in 'his spot', try following that path.
