Qorgyle (first name so far unmentioned) was the 996th Lord Commander of the Night's Watch.
Lord Commander Qorgyle entered the Night's Watch some time before Ser Denys Mallister. During his term, Castle Black used to send patrols East towards Eastwatch-by-the-sea every third day, and West towards Shadow Tower every second day. It was during his time as Lord Commander that Mance Rayder deserted the Watch, at a time when Jon Snow was already living in Winterfell (and therefore likely to have been around 290 AL or a very few years later).
