Thanks for asking 
The lore of Hearth moves around a bit, as each person who comes to the team adds to it and changes it. The only stuff that’s set in stone, is the stuff that makes it into the shipping game. Everything else is mutable as per the needs of the game, until it makes it into the game. That said… here’s the last updated document. It’s not 100% congruent with the stuff in the game.
