Clearly Enshrouded has not gotten enough press... all this happened in early access. It is also ironic that the game apparently doesn't have dwarves.

Hey guys, right now I'm reading The Hobbit for the first time and I was wondering what happens to Erebor after the end of this book because I can’t remember if it was mentioned ever again in the LOTR movies.

sauron doesn't have a big role in the hobbit book ( i guess he is just mentioned briefly as the necromancer ) but in the 3 movies he has a big role that i don't really understand?

why did he want to attack the lonely mountain?

why he didn't want the dwarves to take back erebor?

did he want to make smaug his ally or he wanted the gold or the king stone or something else in there ?

it is not like this in the book so i cant understand his point in the movies ?

( ps: i didnt read nor watch the LOTR books/movies so if spoilers are necessary warn me please)
