Correction: Martin was the OP, not Thewitt. Mea culpa. Thewitt has already published works.
So no elves, dwarves, goblins, Wizards, dragons, nothing of the classic fantasy races?
...Races used in fantasy books should inherit the general characteristics readers have come to expect in those races from the authors who have come before us. This makes a book comfortable and believable. Yes it's ok to deviate from this, but the father afield you go, the more unbelievable your world becomes.
(My bolding) No, it just becomes another kind of speculative fiction. I may not necessarily want to court a readership with those expectations. At the very least, I want to startle and intrigue them with a new take on, say, elves, orcs, sorcerers, or dragons.
Sigh. I've only been on AW for six years, counting lurk time, and I've lost count of the iterations of this very discussion.
Look, some readers are going to say, 'Oooo, goody, more accepted tropes that are easy for me to understand'. Others are going to say, 'God, not again, I'm so bored by these damn things now.'
It's up to you as the author of your own work to decide the tack you take. I could cite half a dozen great novels that use the fantasy-race-trope almost exactly as you propose, six that don't, and another six that twist the trope in some interesting way. What is 'unbelieveable' to one reader is a refreshing change to another.
But that doesn't really matter, because those books are not your novel. You're right, we don't know how you've handled the tropes. We won't, until you either post a snippet in the SYW section or publish elsewhere.
Thewitt*, what is *your* goal here, your reason for asking the question to begin with?
Confirmation? I can't tell you whether the writing works until I see some of it up in the SYW section**. My gut feeling is to avoid anything that smells too much of Dragonlance, Warhammer, and the other Tolkien clones I've been seeing since 1977, but I can always be persuaded to at least look.
Permission? Absolution? No one can give you that but the market and the readers. Every published story is a gamble and a compromise.
Are you looking for a spirited discussion with a lot of different opinions? That, we can do here on AW. But it might help if we knew what you wanted out of the conversation.
