A family through bond not blood, but a family none the less. They are, essentially, the world morphers, able to change their portion at will.
Although it is a trial and error process, they do eventually find a balance between power and grace. Some, such as Ichtytalus, the Guardian of the waters, has nearly wiped out an orphanage when she used to much power on a wave.

There is a High Guardian, who is, more or less, the leader of the Guardians, it changes rarely, but when it does, a new system is sure to come.
Their announcements to the public are mainly when to expect, say, a cave to open up or fish migrations to occur.

When Animoterra was first formed, the group also sprouted, and helped form it into the massive, healthy planet it is today. Caverticus is by far the oldest, but he has not been the High Guardian, as he hasn't wanted a leading role.
Throughout time, other Guardians have emerged, such as Ichtytalus, who was born as a Barbro, but chosen as a Guardian at the age of five. Chosen Guardians are usually trained by the original before their Divergence.
It is still a group today, but if they were to disagree to the point of separation, the world would smash into chaos, and they know this.
"For one we destroy, for all we build."
Although the true date is unknown, Caverticus swears he started when he met another Guardian.
