▶Personal history/Life paths: Depending on the class we choose, let us choose a brief personal story like GW2, Cyberpunk 2077 or Mass Effect series to add a bit more of RPG. This personal story can help to explain why you are a Warrior or a Witch, also you can add that depending on what personal story you picked you will get a personal quest each 10 levels, like GW2.  

Example:  

Witch: Witches Guild – Secret Neutral Organization 

Personal stories 

-Power – You are looking for power, you just want to Be more powerful than common mages, maybe you make a deal with a demon, spirit, or something.

-Vengeance – You were exiled, humiliated and punished by the Magic Police (lol XD) for studying the dark arts in secret, now you are looking for vengeance. Maybe you harmed someone or maybe not

-Freedom – The Witches Guild has members infiltrated over all races and societies that watch for promising members, they kidnap or attract those persons to train them and make them part of their covens. Perhaps you like it, perhaps you don’t. 

▶Skin color: You just read my mind, instead of having 5 different races of Elves (reskinned Elves) as playable races, you can include all of them in one: 

-Sea Elves- Bit of Fishy Scales and blue skin

-Sand/Volcano Elves – bit of reptile scales and green/yellow skins

-Forest Elves – Horn or wood protuberance (like TESO wood elves) and tree leaves

-High/Light Elves – Some shiny human like skin, etc…
