We are Traveler's Trojan Horse to win against the Darkness In Unveiling, Darkness says we are a "means to an end" for the Traveler, and that is exactly the name of the quest that we've been doing the past weeks. So, maybe, contacting the Darkness was all along the Traveler's plans, and it wants us to get Darkness' powers.

Maybe that is to win the argument and make us the final form, etc etc.

Or maybe, it is to make us establish a connection to the Darkness, which could be used as a backdoor to "hack" or "infect" the Pyramids and get rid of them. Our bodies would be the "connection" for our Ghost to "hack". This makes sense, since we have absolutely no idea what Ghosts are and what exactly is their purpose or even their connection to the Traveler. 

Maybe the Traveler stood its ground not because we were special, but because some conditions were met where it could finally defeat the Darkness by this scheme. We are the Traveler's last... gambit.
