The Twelve of Dust

The Twelve are the gods created by Dust.

The Twelve were made one by one and thus each have an associated number from 1-12 which designates the order of their creation. The later one of the Twelve was created, the more power it possesses. To avoid the Twelve destroying one another, Dust created them so that, in order for one of them to exist, each of the Twelve created before them must also exist.

This concept is often depicted as a tiered pillar, on which the bottom-most tier represents the oldest of the Twelve, and each successive tier corresponds to the following of the Twelve. As they become more and more powerful the higher up the pillar they are, the ones below would be unable to fight the ones above them, while the ones above would not be able to fight the ones below for fear of destroying them and bringing everyone above the destroyed tier crashing down.

Parity
It is not yet fully understood what it represents, but just as each of the Twelve have their own associated colors, personalities, names, etc., they also have what has been called parity. The parity of one of the Twelve corresponds to the parity of their number, and decreases in significance the higher up the pillar one is. This is usually displayed on a spectrum, where odd corresponds to the right side, and even to the left, nicknamed right-handed and left-handed.

Onu and Ivi thus have the most odd(right-handed) and even(left-handed) parities respectively, and each pair of the Twelve after them have the repeating but diminishing right-left pattern.

Some have proposed that, the more right-handed one's parity is, the more emotionless and reliant on brute-force they are. This is mostly supported by the observed and learned personalities of the Twelve, but has not been confirmed by a member of the Twelve or reliable Fragment.
