Recently when I was in my former guild someone mentioned a site... Appaerently that site had every single information what you need.

So I said to myself-"Why would I torcher myself and find this fountain myself"

Then I went to that site, found the coordinates, n happy me got lvl up! yaay

Now, the site has coordinates of everything you need, complete quest guide and more importantly, how many subquests it has...

The site is:
