My first level dwarf paladin opts for a "fighting withdrawal" against Ferox The Incinerator.
If your dragon is a reptile, parthenogenesis wouldn't be out of the question. I prefer my magical creatures to be impregnated by the north wind or alchemy rather than have two dragon or unicorns lay their eggs in the river or bone in the moonlight.The Greek sex between two dissimilar creatures is cool though.
So does Vorn have some kind of sees-through-ravens thing going on, like Odin?(I might be misremembering Odin)
Obviously ancient dragons have Clerics....
Certain electromagnetic events can cause the lines of magnetic force flowing through Ferox to close off into loops, which then separate from her. These loops are her eggs. They have the potential over long periods to become sentient magnetic anomalies like her.
Perhaps it's Vorn's Egg? I mean that's some pretty creation myth stuff there.
