I understand that Lady Vox and Lord Nagafen are not Kerafyrm's parents. That is very clear. I also understand why Vox and Nagafen were sent into exile and by whom.
However, there are persistent hints that Lady Vox did, in fact, produce an egg, (possibly more than one), and that there was a failed attempt to smuggle it to Nagafen. I seem to recall though that there are still rumors that perhaps another egg succeeded in reaching Solusek's Eye.
And that, if successful, a new Prismatic Dragon would have rivaled or exceeded Kerafyrm's power.
What are the facts and rumors around this?
