Or, alternately, it is the oldest in the Vale region. I'm wondering if the human-controlled areas rarely have big/dangerous Grimm; this one escaped because it was buried alive; there are ones of similar age and power in the wild, unoccupied regions.

It also implies very strongly that Grimm don't need food and water; they're sustained simply by ambient energy/dark magic/Dust fallout or something. That raises the chances very high that they are some kind of bioengineered weapon and also raises the chances of a non-human (maybe even non-physical) Big Bad behind everything.
