As an avid fanfic writer (with no actual completed or released fanfics), I've worked on a number of Legend of Zelda fanfics. On a recent one, I wanted to Cremia and Romani (rather than Malon), but I've only played a tiny bit of Majora's Mask, and don't own the game, so I didn't know anything about them!
I wasn't about to let a little thing like not knowing about characters keep me from including them in a fanfic. But, this meant I had to learn about the characters first. While I was able to find the information I sought, I had hoped to find an extensive Legend of Zelda resource which I could used to check information on every Legend of Zelda character and location.
Unfortunately, I found absolutey nothing. Time passed by, on and on, world events happened and people aged and aged. By then, a good day had passed since my search began, and I came across Zelda Legends. I had seen the site before, but tend to avoid sites with links to sites which provide ROMs. (Yes, I'm a high and mighty smug elitist like that. I'm also a capitalist who hopes fans of Zelda will buy the games rather than just downloading them.)
There was another Legend of Zelda fansite with a wiki, and I was about to sign up there, but the wiki was poorly done in places, and would take a lot of work to bring it up in quality. So, I decided to check out the Zelda Legends wiki. And I liked it. Unfortunately, it's low on pages of information right now. But it's definitely pointing in the direction I'd hope for a Zelda wiki, and it's not bogged down with a lot of low quality stuff!
I also appear as a Wikipedia user.
I consider there to be two Hyrules. The first is in the OoT line. The second is in the ALttP line and the AoL line (although these take place in different parts of Hyrule). Yes, this does cause trouble with ALttP's lore about Hyrule, but I don't plan to hurt my head thinking about it.
The Four Sword series I don't place specifically in this timeline, but agree with the ordering of:
