Eternals(?)

As the 7 have no physical form, they are incapable of having children in conventional ways, despite being able to take the form of a human. There are, however, "eternal" beings, or so the humans call them, who seem to not age at all and carry much more magical power than any normal human. This is what is happens when the fusion of the 7's powers to create fuse with their previous creation of humanity and Zevian. It costs much less magical energy to create an eternal with a magical alignment than to create another godly power from scratch and since what they have is limited, it is the most efficient and safest way to bring more powerful magic and guardians into the world. Even with this being a much more efficient way to create, there are only 20 some of these eternal creatures created, although they are each very strong and align with a particular part of the mortal culture or state of being.
These people are meant to be an extension of the voice of the seven. Being one of the people allows them to take care of smaller conflicts while the seven worry about larger problems and mostly reflect the eyes of the void from noticing the small homestand. Because of this, it is extremely rare for the 7 to directly communicate with the people save once or twice every few years during celebrations, festivals or if needed, in times of peril.  Once the 7 disappeared, the onus fell on the Eternals to keep Zevian from falling into disarray.  Before the collapse, most of them chose to show themselves to the people and interact with them.  Afterward, however, they mostly stay to the shadows and interfere only when necessary and do so stealthily.  Some isolated themselves, some are in disguise and one or two still show themselves despite the warnings of others (2 maybe? One out of a desire for attention, and one out of a desire to protect --> Gotta be shield bro)
Acadium was a desperate attempt to bestow the power of an eternal plus the knowledge of the void onto an unmarked human. Eventually, the power overtook him and as his quest grew more and more hopeless, he was driven insane. Not any of the other Eternals were aware of the void beyond.
