So in the dark below we met Eris and heard her story of her raid team and how she had Toland the shattered for her team even when she said that her whole team had died she also mentions that she didn't know what happened to Toland during the raid . We know from lore that he had a connection to the darkness so what if he survived and that he makes his way out and warns us about the taken coming . It makes a little sense if you connect this with the voice from the vid doc . Is this theory sound or is there something I'm missing ?let me know would love to talk about it .
