Normally, when Akil brought Setem out to the fields, he would be actively riding the large horse. Unfortunately, today was not a normal day. The effects of last night's overabundance of painful food meant he was still not quite back to normal, and he wasn't going to risk expunging the evening meal on his horse's back.
So instead, he was walking beside Setem, holding the horse's reins for the moment while he found a spot to release them and let the horse run around on its own.
