You don't really ask dragons questions. At least, that's the way that Sam was brought up. So he's fine with Gabe asking questions. It gives him something to think about, anyway.

Sam hums, sitting back and letting his eyes fall shut as he considers the question. "Depends on the sources you look at. Some of them say that all dragons are descended from four who came into being when the world was young, created by the one who set the world to turning as protectors of the land." He glances to Gabe. "Not everybody agrees with that, mostly because that would require at least one of the first to be female and more likely two of them. Still, others say that the other dragons came later, a larger group also created by the one above. Different from the first four, who were more powerful but regarded these new ones as brothers and sisters to watch over."
