Tales and Chronicles
Jewel of the North, formerly know as vincegetorix
The impression I have is that it is intended to be backward compatible with 5E, thus you should use the same names.
And using culture is a very bad idea as it means there is only one culture per race and that it is impossible to escape said culture like a hobbit growing up in a nearby human city.
Well the game uses Culture because they players are all humans from a different culture: beorning, dalish, gondorian etc or elves or hobbits or dwarves from different culture. If you look at the source material, the peoples of Middle-earth were kinda monolithic: Rohirim love horses, the dwarves lost their home, the hobbits live in a cozy hole.
And the mechanics being backward compatible dont mean you have to use the same words! It just means that a character made with 5e can be played in a game using the A5E without to much trouble.
