From a Yellow Zone information pamphlet

Nod: Representative of the righteous and a foil to a corrupt oppressor

The Brotherhood of Nod champions the common people - the 80% of the world's population that struggles to get by in Yellow Zones torn by war, wracked by poverty, and abandoned by GDI. Using Tiberium to fuel and fund our efforts, Nod works tirelessly to bring order from the chaos. We make the streets safe, distribute food to the hungry, provide emergency medical care, minister to those who feel a spiritual vacuum, and inspire hope in people who would otherwise have none.

GDI casts itself as the world's guardian and savior, but they are neither. GDI is corrupt and unjust: 20% of the world's population - the most wealthy people on the planet - live in the Blue Zones, consuming the majority of the world's natural resources, wielding their vast military power to maintain the status quo by depriving the downtrodden of their god-given right to mine and exploit Tiberium.

The powerful oppress the weak in the hollow name of freedom - and the only counter to GDI's power is the Brotherhood. Nod meets strength with strength in the name of peace and progress. Nod is the only hope against GDI tyranny. Brotherhood... Unity... Peace.

Nod：正义的代表，腐败压迫者的揭露人

兄弟会保卫平民—世界80%的人口在挣扎存活在被战争撕裂的黄区，饱受贫穷的折磨，被GDI抛弃。用泰伯利亚作为我们行动的动力和资金，Nod不知疲倦地工作以从混乱中带来秩序。我们把街区变得安全，给饥饿的人分发食物，提供紧急医疗护理，帮助那些感到精神空虚的人，并给无路可走的人带来希望。

GDI将自己塑造成世界的守护者和救世主，但是这两者他们都没做到。GDI腐败不公：20%的人口——地球上最富有的人们——生活在蓝区之中，支配着世界上大多数的自然资源，运用他们庞大的军事力量来维护现状，持续夺走被压迫者天赐的开采利用泰矿的权利。

强者以自由的虚伪名义压迫弱者—唯一能与GDI力量抗衡的就是兄弟会。Nod以和平和进步的名义，用实力对抗实力。Nod是对抗GDI暴政的唯一希望。兄弟会…团结…和平。
