Itomo's plan is to return to the lair of the spider, then follow to the west in the direction he last saw them heading. He will use his ranger skills to follow what I assume is a relatively easy trail to follow, considering they were all for the most part mounted but traveling at the slowest speed of the group (the unmounted.). He is aware that this may take some time. The advantage he has, or so he thinks, is that he is a lone rider who has no trouble making decisions and is not following the ambling leadership of an old mule.
