"???" is the shade "beginner" job. The story goes you sacrifice your "time" to seal the black mage and then you wake up in fox point village on vulpes in grandis with absolutely no clue how you got there, not remembering your own name. The name "shade" is given to you by moonbeam.
That said, it technically is a glitch because, as far as I know, there's no legitimate way to get out of fox point village before being advanced to shade.
There are some events that can let you leave, legitimately.
Seeing as many new familiars are gacha / booster pack only, it would be nice to have a list with all obtainable familiars (by dropping). For example, the Wolf Underling familiar was confirmed by a GM as not obtainable by dropping, and that must've stopped many people from wasting days, weeks or even months at farming it. Also, some exclusive character familiars like Evan's Enraged Golem, Door Block, etc, are said to be only by booster, but Aran's Scarred Bear can be dropped. There's no pattern. It would be really great for familiar collectors and the community in general.
