After a few days on the road, as he starts to near the next city, he senses a presence overhead; looking up, he'll see three gryphons, with riders, making sweeping circles, almost four hundred feet overhead, and about a quarter mile out from him. He'll catch the glint of reflected sunlight off of a spyglass, as well; it's fairly obvious they're watching for him, given that, unless he intervenes, they'll circle for about half an hour, before heading back towards the city.
