The Almighty
The one is also known as the Source, and the true name of the almighty Source is unpronounceable by mortals. This omniscient, omnipresent entity is more like a force of nature than a sentient god, a natural law, something that simply is.
In the beginning, there was only the One who was surrounded by the void, but the one had too-much concentrated energy to be contained, So at the start of existence, it exploded into many different pieces, little shards of the almighty. These pieces are called the shards and the One is the source of all shards, hence the nickname.
They vary greatly in size and strength, and the bigger and stronger one of these flakes of divinity is, the larger the realm they are capable of giving birth to. They create a pocket inside the void but are still surrounded by the void. Their power is like outward pushing energy that keeps the void away, and therefore, the stronger they are the larger the bubble they create.
Shards are all different and unique, and not all of them are even sentient beings at all, some of them are more like their parent, the one, an energy that just is, and some others have achieved full sentience and actively shape their realms. Most are something in between.
Yanu for example, is mostly energy, but differently sentient, at times. Where O is fully sentient and actively creates all parts of her world.
As mentioned before they also vary in strength and size a lot, and some shards, that are too small to have their own world, have either visited or full-on invaded the worlds of others. For these miniature shards, things are very different, they might often choose to manifest as beings, even if they are just energy. If they have the consciousness for it that is.
They might also choose to simply be their own shard, even if it is very small. They could be considered to be like small islands, surrounded by a vast ocean, far away from the large continents, and mostly ignored by them.
Divine Principles
The one created a set of Divine principles which allow existence to, well, exist.
These principles are gods in their own right, Universal Entities, They are Type 5 shards, only they exist in all, rather than existing on their own. They are present wherever the One is present.
Honors
That whose name is unpronounceable, that which is all, that which gave birth to all, and all that will ever be.
