Talk to Zavala
Speak to Zavala in the Hall of Guardians at the Tower.
"There is no doctrine but defense. If the City is to stand, every response must be measured. Every attack calculated. Every body block followed by a devastating finale.
If the City is to survive, it must be unquestioned. The Walls must stand. No matter the cost."
