The Forgotten lands is a place where lost souls go. It happens when a mortal dies but there either rejected By the Highest lands/heaven and The Honorless lands/hell. Or the souls were never guided to Highest land or the Honorless lands which is how they end up in the Forgotten Lands to walk forever until there fade out of existence. The Forgotten lands is and will always be a misty purple color and the grass is a purple grayish color and the trees are endless because the trees go for miles and miles up there is no end of the trees. Its kind of a sad place to be in because everyone will forget about you and you'll slowly fade out of existence. Though the souls can interact with eachother and the souls can watch over there love ones in the mortal world they'll just be like ghost.
