wouldnt make sense as the darkness's main goal is the traveler why bypass us at earth and work towards the sun. i could understand if we heavily relied on solar power but we don't the traveler granted us whatever we needed until it's dying breath. and more than likely it looks like this darkness isnt impevious cuz if they had the power to dismantle the sun and give us complete darkness where many of our enemies thrive we'd be dead already no?
