Vaguely reminiscent of "Memory of Earth" ... up to a point... and then totally different/cool

What are the dragons up to, while the people are forgetting them? Do the people with power know about the dragons? How do you keep the memory box from malfunctioning with no maintenance? (Is it gonna go NUTS?)

Are the dragons sentient? They have magic too, right?

(I love this, it's really cool)
