The Builders are a sentient race of beings characterized by their hardy nature and efficient-mindedness.
Builders seek balance through order and efficiency. Builders are relatively short-lived and reproduce through multi-parented synthesis whereby each parent contributes a portion to the construction of a new builder. There is a theoretical limit of 7 parent builders, but builder synthesis between more than 4 builders is considered extremely taboo.
Builders were once the most populous race of Pixelon, but an over-confidence in their ability to create structures to contain the vyroids led to the loss of many builder cities which could have been evacuated. Those who did manage to escape the vyroids take refuge in Camp Hope.
