When I was in the early stages of the Dragonhost Saga, I'd discuss matters with Róisín and my sister.
On one occasion, I described to my sister one of the features of the setting; that while there are monsters in the world, for the most part they're the outcome of tainted magic causing life-forms to become distorted or merged in some way, as described by a character in Earthfire.
"A monster like the forebody and head of a wolf somehow merged with a boar. It had the heads of both and made the noise of both and had six legs and it moved… I can’t describe how it moved. It wasn’t like any animal or a snake… it was, well, flowing. Like it seemed to have no bones… and it was biting and gouging with both heads, and seeing with both heads, so we could not blind-side the beast…"
But she asked a valid question; why must that change always be for the worst? Can't there be beneficial outcomes? And I heeded that question.
It had huge hands, with three broad fingers and a thumb, and its legs ended in hooves. Thick brown fur cascaded down from its heavy neck like a cape, and its massive shoulders were broader than anyone Yastreb had ever seen, Human or Targrath.
<The Little One said, don’t be afraid,> it said in a deep, rumbling whisper. It seemed to take considerable effort in uttering the words. <But you are still afraid.>
Yastreb glanced at Haaki. She was struggling to speak. Fortitude was looking up at her, his eyes showing anxiety.
<You are not afraid.> It gestured at Dorian. <But... you’re confused.>
Myrallea said, <In our lands, it was said that... when animal and Human flesh was forced into one body by Tainted magic... the result was always an... an abomination.>
Yastreb felt a surge of horror at Myrallea’s words, and runes of defensive magic surged into his mind, but the creature made a calming gesture.
<Not always, Myrallea Moondown. Not for the Tsulath, the Marath, the Davutath.>
At those words, other shapes were emerging from the trees; a dozen or more; and Yastreb’s jaw went slack at the sight of Humans whose torsos arose from the forebodies of horses.
<So often there was only pain and terror, but sometimes... life is not denied.> Huge dark eyes were fixed on Yastreb. <As you know very well, Yastreb Stormblade. We lived and we survived. That is our story.>
There is another plot element that gave me some unease when I wrote it.
Early in book 2 (Stormblade) a mage sets in motion a plan of revenge against his half-sister and their clan, by leading her into a trap that imprisons her and lets him take her form. He's also imprisoned four others to give him the skills to impersonate her - one of them a courtesan, because his sister has a number of lovers and he needs to maintain that part of the pretence.
When I was putting that together, it caused me concern that it might be seen as a negative reference to transgenders.
