From Xfire: “Destiny 2 got a wealth of new content with the Season of the Chosen, a new seasonal update focusing on the Cabal and the evil Empress Caiatal who is trying to consolidate power in the solar system. The season mainly revolves around the new Battlegrounds and the special ritual item, the Hammer of Proving. That said, don’t expect to be grinding nothing but Battlegrounds while the season lasts, since you’ll need to spend time in other activities as well to earn Cabal Gold.”
