Tell me about your different races and how they came to be. I'll start.

In the world of Waeth there exists three races; Humans, Lycanthrope, and Dragons. The Humans and Dragons have been there since the beginning, having evolved from ancestors and what not, but Lycanthrope are a bit different.

The thing with Lycanthrope is that their species originated from a disease of the same name, Lycanthropy, that afflicts Humans. Lycanthropy was created through a joint effort between the Lord Of Plague and the Lord Of Monstrosities, for what reason it is unknown, but knowing them it was most likely because they were dicks and just felt like it.

Lycanthropy does what you would expect it to do, transforming Humans into bloodthirsty Human-animal hybrids, regardless of moon phases. But the thing is that the disease was imperfect, meaning that instead of always descending into blood-craving lunacy, they would sometimes be able to keep their sanity intact, either partially or entirely if they are lucky.

Over time, those who were able to stay sane and survive in their new condition eventually found others of their kind, creating nomadic tribes in order to survive from the elements and from Humans. Another thing of note is that any sapient Lycanthrope that spread their disease were more likely to create more sapient/sane Lycanthrope than their insane counterparts, though depending on the circumstances, this is considered highly taboo due to a variety of cultural and practical reasons.

As for the reason they are basically never seen with Humans other than fighting to the death is that they are quite frowned upon by basically everyone, which makes sense considering that the majority of Lycanthrope are bloodthirsty monsters and a single bite can turn you into one as well. While some villages make contact with them, It's only when absolutely needed, and most are killed on sight, sapient or not.

In recent years, a vaccine for Lycanthropy had been successfully developed, but only the rich or nobility are able to afford them.

As for Dragons, they are in a somewhat similar situation to the Lycanthrope, with most either not believing or don't even know that they are sapient due to how secluded they tend to be and typical Human arrogance. Most Dragons keep to their own with few exceptions, either keeping to themselves or living in small family units.

They are often hunted for a lot of reasons, including wealth, fame, materials, or if they are causing problems.

They are incredibly powerful, being able to breathe a multitude of elements and boasting a thick scaly hide that could shrug off any regular weapon, and as for why they haven't just steamrolled through all the Human kingdoms and settlements, that would be due to their reproductive cycle, only being able to lay eggs every half-century or so.

Dragon hunters are looked at with awe and reverence, being considered heroes by common folk. They often have incredible riches and influence from their experience and title, but any dragon hunters who have been in the business long enough to be assigned to cracking eggs tend to not quite be all together up there. The mourning cries of a mother dragon seeing her precious egg splattered across the ground are enough to etch nightmares into any well man.

And Humans, well, what do you expect. They're Humans, doing all of their Human business, Humanning all over the place...

Alright I haven't gotten to the Human cultures much, but I'll get there eventually.
