Builder

The Builders were the highest rate of the Forerunners, considered to be the most powerful in terms of intelligence, wealth, and political power. Builders achieved their power during the human-Forerunner war, as they supplied the weapons. As their name suggests, the Builders were responsible for designing and constructing the myriad technologically advanced structures and objects seen throughout the Milky Way galaxy, including the Halo Array. The chief of the Builder rate and all its guilds was known as the Master Builder. The Master Builder was often considered the most powerful Forerunner in the ecumene. Builder forms were generally tall and sturdy in build, but more refined and sophisticated in appearance than Warrior-Servants.
