The Cave of Black Echoes is an area within the Ninjago Caves. It can be accessed through the Cave of Ancient Ways, via the tunnel with red banners. Within the Cave of Black Echoes are the Fire Shrine and Earth Shrine. Players first encounter the cave when Cole fears that the skeletons have broken into the shrines to steal the golden weapons. Sensei Wu confirms this, and sends players down into the caves to stop them.
