The bridge isn't particularly steady, but it doesn't have to be. Alaedra's skill lets her run across just fine, not even losing her balance for a moment. The pursuers, however, are not so adept at moving, one trying to run but slipping and falling off the edge. The other slowly makes her way along the bridge, determined to catch the drow eventually. The male one, having fallen, then throws a chain to the bridge to hold on, swinging across like a jungle-dweller. It looks, however, like he'll be entering the tower at a random lower point.
