We must reckon with what we have done to our own blood.
-- T'Challa (chapter 1)

Importance: T'Challa thinks this after being attacked by the miners under Zenzi's trance. This is his first admission that currently the greatest threat to Wakanda are its own citizens.

For out of the rage shall come another Wakanda. And a better and brighter world.
-- Tetu (chapter 1)

Importance: Tetu says this while revealing his large army to the reader. This signals the violent means Tetu is willing to take in order to achieve his goal of establishing a new order in Wakanda.

No One Man.
-- Ayo and Aneka (chapter 2)

Importance: This is the message burned into the ground after Ayo and Aneka liberate a village from an abusive Chieftain. The phrase recurs later when it appears in blood on Lord Mandla's chest after he has been killed. This phrase shows Ayo and Aneka's main motivation: a nation cannot flourish under the tutelage of a single King.

Power lies...
-- T'Challa (chapter 2)
