The Humans where the youngest race in Azeroth quickly establishing kingdoms all over the eastern Kingdoms.
Now only Stormwind remains as the rest is destroyed. Yes KulâTiras came back eventually, so i guess there are two.
When you are Level 1 you are a simple man, a common man, ( not RP) and you venture out into the world in search of glory. Your Joureny caused your death, you died a horrible death against vile creatures of epic proportion, probably Murlocâs. It is then you find out your soul is immortal and a spirit healer keeps sending you back to your corpse. Or it can even rebuild your body, at a cost.
From there on the Simple human became, somewhat, of a hero to the alliance. Solving problems allover the Kingdoms and Beyond.
You destroyed the Scourge in the plagued land. You saved redridge from Gnoll and Orc invaders. You rescued the poor people of Elwynn and westfall from the defias, a problem created by the nobility of stormwind,
And from there on after your name became known in the Alliance.
When they ventured to outland, after the scarabs and stuff where defeated, they called upon you to find out what happend with the expedition. THey put YOU on the frontlines during the invasion of Northrend. And as your name and fame grew so did your hero status. When the Cataclysm started the Alliance leadership did not hesitate and send you into the world to find out what happend and how to stop it.
And it doesnt end there.
Your Glory, Your hero status came after Pandaria, when YOU saved Prince Anduin from certain death at the hands of the Vile horde. And when the invasion of Draenor had to begin you where given the command of a Garrison.
A Wonderfull decision because, yet again, you saved an entire world from doom and destruction. As the dust of draenor settled the Legion invades azeroth, but only like one zone so it was kinda dull, and yet again you stood at the front⌠you know where i am going with this.
Humans, Dwarves Gnomes, Elves All of them where simple, normal people finding out they where special and their fame and fortune grew within the alliance.
Now in BFA You are a Champion of the Alliance, A hero, A saviour, a Legendary. And they adress you as such calling you Champion everywhere you go. Everyone knows your name because you are the Legendary Heimdarm!.
As for RP You get to make your own choice. But this is a bit how things worked out
