During the battle with Kovira in the Spirit Wilds of Republic City, Avatare Korra uses the Avatra State to protect Kovira from the Spirit Energy Canon blast. This tore a hole between worlds, and transported the Avatar and her friends through the weakened barrier between not only the spirit world, but also the world of Thedas.
Arriving in the village of Haven, and surprising the few remaining guards of the Inquisition, they discovered a world that was both similar and yet different to their own.
