Before the Breaking of Wisdom
Have you ever wondered…
We have almost all played the game The Legend of Zelda. But how did each dungeon get full of monsters? Who put the fragment of the Triforce there? Who put the Guardian inside? Why put the exact weapon needed to defeat the Guardian inside the very same dungeon? We have all wondered about these things. This campaign is how it came to pass, years before the very first Zelda game.
Take your party to the world of Hyrule and do what is needed to be done to prepare the next generation for the darkness that is coming!
After that, take a look at your wiki. There is some more helpful info there.
