"A powerful dungeon with a large treasure hoard is finally capable of reproducing. The precious metals and gems of the treasure are fused and compressed into a single egg, from which hatches a baby dragon. The dragon matures quickly, and having reached its full-sized adolescence, it leaves the dungeon to seek out new territory."
The Gaia hypothesis writ small.
The idea's certainly come up in the Discworld books, although talking about cities and shopping malls rather than dungeons, as I recall.
