It's based almost entirely off the visual, but the Void looks like a whirpool (Also assuming the giant purple spot is the Void mentioned in Nexus of the Void). The rocks in the upper corner are breakingoff towards the hole, the ice floe is heading towards one of the cracks, the river is falling into a crack… though also coming out of one maybe.
So, giant hole in reality, pulling things in, why doesn't it grow bigger? Is it simply that size and only that size or is something keeping it from ripping open and taking much more down into its depths? One of the jobs of the Virtuoso could be to maintain balance, to set boundaries on the edges of the Void to prevent it from growing too large.
Wish I could mutli-quote
About the Scholar and his stone… It was never once stated that the stone the Scholar is carrying is the exact same stone the leylines led him to.
It is more than possible that given the Scholar's nature and ability to manipulate Leylines he was able to take an Oblivion Shard and shape it into a different stone… Oooh… The Southwest Sentinels found their stones during Chokepoint's attack on Ft. Adamant. Before that they sent a message to the FV about a bunch of stuff they learned. The FV receive the message, eventually decode it, but Chokepoint already left Ft Adamant with whatever she was after. Termi-Nation arc tkaes place as Untiy, Bunker and AZ fight Chokepoint. Then OblivAeon and his Scions begin attacking, Ra makes his last stand at Ft. Adamant, the heroes study the shard, they hear from one of the Scions. What if it is after that point the Void Guard shows up?
My point. How long did the Sentinels have their shards before they became the Void Guard. All for out of space-time metamorphosis, as that is a possibility. Akash'Bhuta ends up with a shard, spending time gathering power from it and it changes her and itself, since the purple crystal growths on Akash'Darsha are very different from the shard. The only other people we see handling a shard are the Citizens of the Sun, who grab and run, and Dawn only has hers for… hours maybe? What if the stone and wielder effect each other, shaping the stone by the weilders nature and understanding. That would explain how Writhe has a small crystal in his head but Mainstay has a giant boulder on a chain, yet those shrds are suposed to be equivalent
Maybe the ley lines led him to the stone that he made into the stone he has now.
We have other discrepancies too, for example We have Greatest Legacy fighting robot soldiers, but before that we had the war zeppelins. I don't know if they retconned some things, or if they are both true, like War Zeppelins carrying robot soldiers, or maybe they were different times they fought.
So, when those lines drew him to a mysterious, glowing stone, he knew it was right and proper to take it with him. The stone allows him to twist the lines, rather than just perceive them, and he can now easily transmute objects into other materials
Maybe it's not explicitly stated, but the way the bio reads, it's the stone he found that allows him to transmute objects into other materials. Thats what his Philosophers Stone is supposed to do, the one he evidently "made".
Don't get me wrong, the idea that Christopher could be purposefully blatently misleading in these two sentences is not lost on me.
But If the Oblivion Shard he found is the thing that allowed him to transmute objects, then why did he need to create a Philosophers Stone in the first place? It starts to break down for me here and something doesn't add up.
So it seems to me pretty much confirmed in the Q&A that the stone Scholar found was in fact an Oblivion Shard and he used it to create his Philosophers stone. This holds consistent with the theories we have on the Void and his Infinite Void promo, and the fact that there have been at least 2 instances of Oblivion shards in the story prior to the Void Guard Release. With confirmation that the toy ape does not hold such a shard, that leaves the two being the one Scholar found and the one that created both Infinitor and Capt Cosmic.
Also there was some solid Adept info too. Argent Adept indeed harnesses and controls the power of the Void through his music and it certainly takes a lot of strength to do it.
A possibility : OblivAeon uses the void as his source of powers.
He exploits the power of the Void - this gives him his incredible level of power. Maybe he does it through somekind of highly advanced technology or magic, maybe by "condensing" the void into the Shards.
And maybe the Void, if it is sentient, empowers heroes to try to escape his binding by OblivAeon. Or, if it is not sentient - and just a mindless "force", is just "used" by heroes/villains to gain more power - but with potentially dangerous side effects, like trying to harness the power of a radioactive source.
We know nothing about OblivAeon and the source of his immense power yet. And look, the Void is now mentioned everywhere...
Here's my guess: The Void is the ultimate source of all things. Oblivaeon came from it, as did the other being who made the Bet ( and maybe Jansa vi Dero, if she's not the same ). Our universe does not come directly from the Void, however, but indirectly by way of the primal gods who arise from the Void. So, I don't think Oblivaeon has bound the Void, he just draws upon its power by virtue of being a primal god born of the Void. He *might*, however, seek to destroy the Void, so there is no Void, merely Oblivaeon. I don't think its certain, though, he may "merely" wish to destroy all of Creation.
Under this theory, Oblivion Shards are sources of vast power because they are essentially fragments of Congealed Infinity. I suspect that a similar mechanism is how the Terminarch creates new Endlings: they aren't merely the last of their races, they are invested with a spark of the Infinite Void by Jansa. It also means that not everything cosmic arises from Oblivaeon, and its possible to have cosmic power not tainted by Oblivaeon. You just have to either get it from a different god, or straight from the Void, and all said options have their own drawbacks.
