I had a look. I like the look of these and it is good to see Bytopia get some love
A couple of 'mechanical' things I noted.
They both have the same speed, so no need to repeat. Place it in the 'both' section above, or was the 'Ban' supposed to have a reduced speed?
The spellcasting seems a little odd. I did not expect to see Produce Flame there when reading what these guys were. Same with Identify for the 'Amn'. Not sure it fits the theme, but obviously you do, so I was just wondering your thoughts on that.
Then, there is the spell Mending, which does fit the theme, but I am still not sure it is needed. It seems odd for all the 'crafts people' to be able to just magic their way through. Why develop craft skills when you can just repair via magic? Because some group can do something, I don't always gel with them getting magic to do it better. But, again, that might not be a prob, and at least it fits the theme I was picturing
Kudos on developing a whole new race, and yes, the genders as subraces is an interesting concept
