It has potential, but let's do some notes beforehand :
1. I recommend don't drag all the warcraft name of the races (though they are common names). I'm more on this for the (night and high) elves and undead to be honest. Better get creative
2. You might want to consider some proofreading from grammar experts. Some typos are quite noticeable, though not a big deal, at least for now.
3. Since it's only an early plot, I cannot say much for the story. It's kind of mainstream.
4. Umm, isn't the way the father tell the story is a bit... complicated for a child?
