I opened two slots and then eliminated the slot count and have accepted four of the batches to be the next three Synths. (No, that's not a miscount.) They will be as follows.
Biosynth 15
Esix, Sentient Spider (m) / Inasnath, Dragon Mutt (f) / Muse, Unicorn (m)
Biosynth 16
Ninjouzata, XenoHathian King (m)
Biosynth 17 - Genesis Two
Dtande, Yautja (m) / Unknown Biopool
Breeagh, Koha Riihan (m) / Lerlande, Yautjadragon (f)
Chevonde, Yautjadragon (f) / Nairne Timu, Dysiniu (f)
That's right, Genesis Two! I got two Yautjadragon applications and HAD to accept them both. One of them is Limited count, too, so I'm nesting them together with a batch of purebreds, and voila! Genesis Two!

So! Baka owes me a Prestory for 15, Rachael owes me a Prestory for 16, and both DF and Sil owe me a Prestory for 17. DF, Sil, don't worry about your clutches being nestled together--just write your Prestories however you envisioned them and I will post them together and add a blurb of my own to tie all the clutches into Genesis Two.
And yes, this does mean there will be xenodragons and Yautjadragons occupying neighboring Bays at the same time. Trust me, I know what I'm doing. X3
Apologies to all whom I couldn't accept--I hope you'll reapply next time applications are open!
