So that explains Becky

Interesting read. The lore dumps from these bios are always welcome additions to your world. As a side note relevant to this one, I do find your approach to interspecies children in your world quite interesting, although it means cases like Marcail and Elara should be more common. Becky is a clear once in a lifetime case, though.

On that note, I’m reminded of a game I once played that took a near opposite approach to interspecies offspring: Solatorobo: Red the Hunter. Though it mainly focused on its own story, it did try to flesh out its world through unlockable lore dumps. One such tidbit clarified that if you had a couple involving both anthro species of that world, Caninu and Felineko, the offspring could be one or the other; both options were possible, but it was a binary thing, one or the other.

I did see this again when I became a brony: one particular episode established that pony race genes could remain dormant in bloodlines for many generations before surfacing, but the fact was that a pony was born into one of the three races, with no hybrids. Alicorns are a special case: you either have cases where someone was made an Alicorn down the line like Twilight, or cases like Celestia and Luna, where they were born as a pony race entirely separate from the rest. Alicorns are entirely separate from the main pony gene pool.

Call me crazy but maybe the drug Grace and the band members took before the gangbang made their DNA or body so instable, Grace get pregnant by all her partners.

Anyway, I'm glad to learn Rebecca/Becky is a duck as a base. I was seeing her as a chaotic chimera, impossible to comprehend.

well give's more idea's.
