Forgotten

What happens when someone is forgotten? They disappear. But what about when it's the other way around? What happens when someone disappears? Are they forgotten? When Judal randomly disappears and no one is able to find him for almost a year, is he forgotten? Al-Sarmen doesn't seem to care anymore, and the Ren Family seem to not even know who the magi is. The remaining magi seem to be going just fine and the eight generals seem to be busy with other villains. So maybe when someone disappears they are forgotten. Maybe no one even bothers to go search for them. But, there always has to be at least one person that cares. Maybe that would explain why Sinbad has recently gone missing as well.
