Proterohistoric Eon

The Proterohistoric Eon is a period of history appearing on the Universal Timeline. Lasting from the creation of Ha'ther until the Great Temporal Barrier, the Proterohistoric Eon contains the oldest events to occur in Ha'ther.

Most notably, the quintessential elements were entirely absent during the Proterohistoric Eon; in their place, the proto-elements were used for material plane construction. These elements were, in general, extremely reactive.

Very few lifeforms existed during this time. Other than the Elder Gods, the only known beings were a handful of celestials and the proto-elemental titans.
