Erevos

Erevos is the mightest and biggest of all the Essence Shards that were made during the creation of the universe by The One. Differently from the Essence Shards left by the Light of Creation, Erevos was created simultaneously with the birth of the Aeons. While the Light of Creation shattered into the nine Aeons, the Shadow of Void solidified itself, becoming Erevos.

The major feature about Erevos is that it isn't a bright spot of light, instead, it's a black and purple twister of negative energy, resembling a black hole. It's often described as beeing darker than the void.

The nine Aeons were born with a natural aversion against Erevos. They understand that there must be balance in the universe. To have creation, destruction must co-exist, even if trapped inside this massive dark star.
