According to Raoudha and Ra'am, there may be a small camp of refugees lurking somewhere in the southwest, somewhere near the road to Castiblanco. With the Knights Templar set up in Castiblanco, they are worried what may happen if these refugees are discovered by Castiblanco forces. If these people seem trustworthy, then Cijara desperately needs the manpower. However, Cijara has no one but women, children and newcomers to guard the walls. If these people are interested in helping themselves at Cijara's expense, then they must not know how easy it would be to do so.
