Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi! I need help with something. Well, english it isnt my main language but i think that i can speak it(spanish guy).
So, when i do the quest i want to read the story of them but some time i cant understand what does it says and my question is: There is any way that i can change the language of the game to spanish?

Eyyy! I'm a spainish bro to. I ironicly know no spanish. For your question, Unless you find a 1.12 client to support it i don't think so, you could always use google translate for the story (I'm unsure if using a spainish client is against TOU. It shouldn't be if you still speak english to everyone publicly.) You should be able to find one that supports spainish easy on google.
