Hm, I guess we can't do this specific part anymore, since we now go to Rook from Dawnport and start our journey there on the Cipfried temple. Your method is only doable if we manage to find an old char that never passed the bridge that enters Rookgaard (i. e.: one that was created and left alone on Santiago house)
Edit 03/11/2018: Well, I guess it means that currently there is no way, right? I asked it thinking about a valid and actual way for nowdays...
