After many years of struggling to survive against hostile humans, even traveling into an alternate dimension with the help of a powerful wizard, the dragons have come up with a daring plan to preserve their species. Taking female humans, they will take and convert samples of their DNA into SEDNA (Spiritual Equivalent of DNA) and send them inside her body, causing the human to give birth to a dragon in human form!
Surely, this will bamboozle the dragonslayers, which will likely see the resulting children as powerful mages and nothing more. If they use magic to try and identify these kids as dragons, they'll find no evidence and assume they are regular people (as far as one can be regular with powerful magic).
However, the dragons has come across a little snag in logistics. How on Earth are they going to get female humans to agree to this? So, my question is: What is the best way for these dragons to recruit/obtain women for this purpose?
Assume humans, in general, are anti-dragon due to government propaganda, and that there are only two sapient species, human and dragon.
Also assume that dragonslayers, in order to protect their women from dragons in human form, set up a sort of '9-1-1 network' that allows a woman to alert the dragonslayers if she has a dragon problem, causing a squad of dragonslayers to teleport in and deal with the dragon.
This network is powered by a special rune, tattooed on during childhood, that allows females to telepathically 'call 9-1-1', so to speak. Since it's mental, it's just about impossible to stop, and so the dragons really want to avoid conflict and gain consent.
