Zavala greets you with a grim but hopeful smile, "I'm impressed. You've more than proven yourself worthy of the Guardian title…. I wish I could tell you it gets easier from here."
He turns and looks out at the Last City below. "Humanity needs our help now more than ever, and we need Guardians like you on the front line."
"Right now, that front line lies at the precipice of our very existence: the Pale Heart."
"We've devised a way inside the Traveler to break the Witness's hold on it. We have only to take the next step forward."
He turns back to you, a spark of defiance in his eye, "It's time to face our greatest enemy head on. Join us."
