The public run of Sehto only had 17 sessions and was split over four plotline strands (of which Vestur around Togi can be considered the main one), played by participants of the facebook application Send Pokemon. The information from that run can be found publicly online at http://sehto.pinkgothic.com/sessions.php
It can be considered a canonical Sehto run, though unfortunately did not progress far enough for details in anything but physical setting to arise.
