[@MrDidact] I would, with your permission of course and oversight, create a character that is a quasi NPC/PC, controlled by me and by extension, you, through post review, direct control via yourself, and any applicable guidelines. As for taking on the South, that is not exactly what he is trying to do, but rather, build a sizable sphere of influence beyond the wall. Have him starting off with a sizable tribe compared to those about him who still remain, but focusing mainly on raiding and subjugating other tribes/clans in the area, with different types of raids to the South from time to time. I will make a rough draft of sorts when I get home from work, to let you look it over and mull it over.
