I like the Olympia trick for the name problem. Open up the wikipedia page for the Olympic team of the country you are looking for and mix and match the names you find there. You can even go by years, to see what might have been popular.

Or you can use names from historical figures related to your setting/topic.  If you read David Weber's Honor Harrington series, AND happen to know a few names of who's who in the space sciences, you will see a lot of (last name) connections.  Mr. Weber clearly uses lists of space science inventor/researcher last names for a lot of his characters.  He also re-used a lot of names between the one-shot Path of the Fury and the Honorverse series.

So, even if you do not claim any sort of relationship between your characters and the real life characters with similar names, anyone who DOES know the history of the art will recognize that you, the author, see a connection.

(Jim does this with Harry as well, but it's a LOT more obvious.)

I have been slack, not reporting my writing recently.

Set In stone has been updated several times:

Chapter 24: 5700 words
Chapter 25: 4400 words
Chapter 26: 5600 words
Chapter 27: 7700 words
Chapter 28: 11200 words
End of Act III

Total word count is now 178,600 words.

Next chapter will be the epilogue, then I'll start to edit for publishing.

What do you mean by blog fiction?  I am posting my rough draft on wattpad (https://www.wattpad.com/myworks/44462558-the-crimson-artifice)- is this what you are talking about?

So far I haven't been impressed with this method of exposure.  At least, it seems to be difficult to garner any attention without years of previous exposure.  I was inspired by the success of a writer on wattpad who was signed to a major publisher after getting millions of views to his story, but he had been on there for a while previously writing fanfics.

I use Wordpress myself.  Never heard of Wattpad.  When I attempted to start reading your story, it tried to make me sign in.  I couldn't read beyond your introduction without signing in.  This means I'm not reading it.  Maybe that's just me, but I don't think so.

Here's where my most recent project is, if you want to see the sorts of comments I'm getting:  https://setinstonestory.wordpress.com/2015/01/25/chapter-01/

You can also see that not all fiction sites are the same, because I have ALSO been posting the story here:
http://royalroadl.com/fiction/1246

Royalroad has a lot of readers, but the audience is more focused on light novel styles, reincarnation, and protagonists-in-a-game fiction.  I get very, very few useful comments from there, though the readership numbers are not terrible.  Also, once you drop off the top pages of recent posts, unless you have a large following already, the readers don't find me often.  They are searching by tags, and my work doesn't have the tags they want to read.

Something like Jukepop might be interesting.  I am looking at that for my next project, since Wordpress is doing horrid things with their backend.  I plan on writing at least one more project as blogfiction before translating it as an e-book.  After that, I might start poking some of my most vocal readers and seeing if they want to do beta reading for me.

I am not certain how Jim feels about Baen's Bar.  Yes, that Baen.  Their official forum.  You can post whatever you want in their generic slush pile, and people will read and comment on it.  One chapter at a time, or perhaps a short story all at once.  I won't link it.  You can find it easily enough.  Just remember to put it in the generic slush pile.  Also remember that the slush pile ONLY contains content.  Every slush pile has a paired thread for comments on the contents of the slush pile.  You post a chapter in the slush pile thread, and then post a request for review and any specific requests you have in the slush pile comment thread.  Clearly naming the thread posts the same is a good idea "My Story Chapter 1" in both threads, is best.

Is there any specific requirement that the demon's natural form has to be so squick?  If it were me writing it, I would have the demon's natural form be more human, but give them the ability to take on a combat form that is unnatural to them, and very inhuman.  The sheer effort you are going to have to put into making the relationship believable without creating a lead that nobody can identify with is going to be daunting, unless it's a central theme to your book (Don't judge a book by it's cover, beauty is more than skin deep, etc.)

As a middle ground, you could perhaps arrange it so that the sorcerer doesn't know what the real form of the demon is.  If you wanted to go even further, the demon might not know what her true form is.  It might even be that her primary form is slowly defined by exposure to others.  As the years go by in exposure to him, she might find it harder to change into the squick form.

There's a lot of ways around this, but you are going to have to be careful.  Beauty and the Beast worked, but the Beast was a lot more human than this demon is in her inhuman form.

50,000 years is a lot of time skips unless the story is really, really long!

Is the lead immortal?  Perhaps a god?  Telling a bunch of stories about a god trying to keep up with humans as technology advances could be fun.

Deity: What is this stuff?
Human: We call it 'writing'
Deity: Hrm.  So what else has changed in the last few thousand years?
Human: Err, I'm not sure.  I've only been alive for twenty years.
Deity:  Follow me then, by good friend, it's time for adventure!  You can write what I do with these 'letters', right?
Human: Yes.  I can, but I need clay, and a fire to harden it after.

And so on, every couple thousand years. 

((yes, I know people couldn't write 50k years ago.  Neanderthals were still around that long ago ))

Wouldn't a reduced supply in the face of normal or accelerated need in a rice-based economy just be inflation?  Each unit of rice has a value.  If there is less rice, the value goes up.  Sure, if it gets too bad, everything goes into the crapper, but gold also fluctuates in supply as well.  A new gold mine, or gold shipments lost at sea, etc.  If the price of staple food and goods goes to extremes for whatever reason, economic shenanigans happen, even in a gold economy.  The great depression took place when the US was on the gold standard.

In a high fantasy scenario, I can't imagine many ways where normal coinage or raw materials would be viable for an economic base.  People could counterfeit it too easily.

What I could imagine is an actual trade in mana itself.  Magic potential.  You might be able to take it from other people, but you literally couldn't counterfeit it.

Magically gifted people could be rich, if they wanted to be.  Magical creatures might be absurdly rich, if they wanted to trade away their magic to humans for goods.

Dragons might simply hoard magic power, making them highly irritable.  First you bother them, then they realize they have to expend magical power to kill you?  *grrr*

Magic potential would then be a great deal like a rice economy.  People would buy commodities with it.  With effort, anyone could make/grow some, but most people won't bother if they aren't good at it.

Heck, with all these ideas floating around, you could probably create a 'Sam Spade, High Fantasy Investment Banker' story, completely based around the currency system!
