Alright. I'm done looking at Bringer of Nothing.

Slade, Celaira, Yosh? Gunna need your help making this work. -nods- 

[quote]Age: unknown; presumed as old as all original demons[/quote]

Despite what it says on the timeline, [i]Lilith[/i] was the first demon (not Lucy) and is the mother of all demons. Lucy was just the first demon that Aaurus fell in love with and later made divine offspring (humans, go figure). Anyway, Lilith's first generation of demons would be known as the Original Demons (by angels and later, humans), but among demons, including themselves, they would refer to each other as Firstborns. Additionally, no demon can be older than 9,014 years, because that would make them older than Lilith. So stick to an age somewhere... between 9,000 and 8500. 

Additionally, the Bringer may or may not know Baphomat, Lord of Knowledge and one of the Firstborn. Talk to Synthorian for more details on him (or Lilith).

[quote]Race: Demon (ex-Archdemon, now a Hexwulfen parasite)[/quote]

I don't mind you trying to expand on established lore. Keep in mind, however, that Demon Lord has been the highest title and height of power for a demon. They rule regions in Hell and are very good at it. The term archdemon has never been used, but perhaps it could be established as an old forgotten term that existed before the kingdoms of Hell were made. Sort of like a Lord of Them All...? But then Bringer died and nobody has tried to rule all of Hell since then. So, unless Slade, Celaira, and yoshua (or other Veterans) see a problem with that, we might go with that term (archdemon) having that meaning.

I reckon there might be a problem with it, given parts of Szayeis's kingdom's backstory and how part of it has always been there in Hell. Or something. Yoshua will have to explain that. However, given that Bringer is no longer an Archdemon, this might not be an issue.

[quote]Appearance: His actual (and original appearance) is unknown. When he had it's own form as an Archdemon, his favored forms were a shape akin to a shapeless nightwalker with fierce red eyes[/quote]

Be careful with taking liberties with Nightwalkers. I'm not saying that you are, just.. talk to yoshua171 about this to make sure it's okay. My impression here is that you're using the demon race as a metaphor of sorts.

[quote]a sense of [u]hi[/u] were every constant-[/quote]

A sense of what?
 
[quote]Social Status: Ex-Archdemon. His position and kingdom were lost-whether forfeited or taken,it is now known only as rumor and not as fact by all save those involved-long ago, before he last entered the [u]Abyss.[/u][/quote]
 
If we decide that Archdemon was a Ruler of All of Hell type thing, then you'll need to change the first sentence to something talking about his kingdom being divided up in the cardinal directions. 

Also, change the Abyss to the Void. The Abyss is something else (See Rtron's Mary) and I'd rather not see terms confused here.

[quote]Abilities: As a parasite/symboite, he seems to no longer have any abilities of its own. Rather, his own essence seems to bleed out into and infuse its host's, Nen's, granting and/or transforming him abilities related to what he once bore-or may have, had he continued.[/quote]

This is a bit vague, sir. I would rather it not be a license to pull anything out of thin air for Nen, so let's see a list of Bringer's extraordinary demonic magicks.

[quote]Among the abilities that he did have were the ability to shapeshift into a colossal serpentine, razor-edged-winged dragon that breathed something akin to a blast of ether and light that, even being utterly demonic, could only be described as angelic and heavenly, even as it's effects were like hellfire and lightning. Hence his titles relating to heaven and light, even for his omnicidal and malicious nature.[/quote]

This is fine by itself, but I want to see a (numerically expressed) maximum size, length, and weight for that dragon. ^^

[quote]Biography: An original demon, he was created with an absolute dedication from the outset and quickly consumed so much essence as to become one of the first Archdemons. Even then, though, he was insatiable; unlike so many others even among the Archdemons, he did complete only a handful of evolutions-he completed dozens, at least, and, over the course, he devoured pieces of even his own soul in order to grow.[/quote]

Okay, perhaps we could go the route of Archdemon just being [i]another[/i] term for Demon Lord. That'd be easier. Up to you, though.

That last part, however, is not possible. If demons could evolve into a more powerful demonic form simply by eating parts of their own essence, they would have no need to consume other sources of essence (even if it's demons). There's a reason why humans have higher qualities of essence (and angels even more). So take that part out, please. I don't mind if you use self essence eating to mess up Bringer's emotions so that he only feels hate, but not for evolution rituals.

[quote]He seemingly posed little genuine threat, though, as he was unconcerned with anything less than a full apocalypse and so actually rarely caused any significant damage, and, as he was constantly latching onto human hosts and evolving or caught in the Abyss, he would effectively disappear for entire lifetimes and was absent from his throne in Hell[/quote]

Change Abyss to Void, please. And hmm... throne. Perhaps one of our current Demon Lords would like to take up Bringer's old kingdom after he died. But here, it sounds like Bringer kept coming back to claim his throne after reincarnating and evolving back up to a higher demonic form. Is that right, Nevis?

[quote]It is theorized that, were it indeed a host of demons that destroyed Chime, he was among or even a leader among them. It is known that it was shortly thereafter that he apparently planned to become more active and, for some reason, several demons and Archdemons collectively assaulted and injured him-or killed hist host body, depending on the version of the story told. Some theorize that the attack was because he was nearing or had already found a means to actually annihilate essence. In any case, he failed to regroup and take a new human host and was lost to the Abyss.[/quote]

I don't mind that Bringer was in on the action that took down Chime and Heaven's Gate. It is fact though that Krengius the Fleshshaper's abomination is the one that destroyed the Gate. So keep that in mind. Again, change Abyss here to Void, please. 

Hmm... annihilate essence? As in, completely destroy the energy and soul that make up essence? No. Take that out, please. 

[quote]Even attempts to contact him across the void were exclusively met with failure. several decades ago was there any stir or sign that he even existed anymore-at which point a clairvoyant angel assigned another to watch over two seemingly unconnected humans.[/quote]

I'm not sure communication is even remotely possible. ...-pokes Yoshua, the Void expert-

Also, fix that sentence structure, please. It hurts my head.

[quote]Finally, years past, the Bringer of Nothing seeped across the Abyss and spawned in the one being that was ever his own, his own kind, his own kin-one who felt as he did.[/quote]

It's mostly the wording here that bothers me. It sounds like the Bringer escaped the [s]Abyss[/s] Void. But no, he reincarnated and took over the child, right? Escape is not possible in the Void until it is 'time.' Again, Yoshua, please look at Bringer of Nothing's entire CS and help me help Nevis make it cool.

Welp, other than all that ^ Nevis, Bringer of Nothing sounds like a fascinating bloke. ^^

Please stand by for Yoshua and others to look at it.
