Some responses to your reply, Haraldur:
It is not merely propaganda, it is a long work that covered the whole of the cavern, and long works can be convincing, especially when people have those same thoughts half developed in their heads anyway, which is quite likely in an oppressive society (which the demon society almost definitely is, what with the power struggles between Qor, Abodahon and Iban...). Also, they are not "suddenly living in harmony". They are organising, preparing for a struggle.
Let's take a look at what you wrote:
As the writing finished in the cavern, a long essay that completely covered the walls, the demons finished reading. Everything had made perfect sense. They had a discussion about who might have written the messeage, and whether the person was trustowrthy, but came to the conlusion that, since it had made so much sense, they should take it as true anyway.
This is where the "suddenly" comes from. They're deciding this right then and there, imediately after reading right? (And in one post.)
They then discussed how they should organise themselves to build a better society, and then commenced to do so, to organise themselves. The market traders dumped all their goods into a nearby warehouse, and there was an election as to who would have the responsbility of distributing stores from that warehouse.
So now they immediately take action on it (in the same post).
Traders dumping their goods for the good of the many isn't very believable at all. These would be the ones actually worse off by the change, and to think that they would all agree isn't obvious at all. And it is never mentioned why they would want to do this. "Hey, let's drop everything and all share our stuff and build a better society!" Isn't very far off from "suddenly living in harmony".
A few of the hungriest demons then rushed towards the warehouse where they were provided with the food they needed.
Yay! Harmony~!
With the demon blacksmiths going about their work quickly, the demons started arming themselves. Meanwhile, word of these developments spread quickly through the underworld. In the areas where some demons tortured dead souls for a living, they stopped doing so, apologised to the souls, and then both they and the souls started to build a new society,
"Dude! I am sooo sorry I tortured you for the past eternity!"
"It's cool, man."
"*Sniff* I love you, man!"
"*Sniff* Give me a hug!"
...
Just totally out of context...
though notm however, without a few arguments with former tormentors.
Okay! This almost saves the post. But it's way too little. This radical of a change would spur quite a bit more than a few arguments, I would hope. (And it would have to be a tremendously radical change indeed, even more so than on Gaian, if the place is literally called "hell".) And what happened? This could turn out to be a cool storyline if this one post were uncompressed and composed an entire chapter, perhaps. The story is in the details (which is what DAL is about-- the story). The end result doesn't really matter.
Demons you say? What about them? They are obviously intelligent creatures, and peaceful enough not to have annihilated their species. They are intelligent enough for people to want to rule over them. The only demons who have really played much part so far have been power hungry brutes, though not mindless: Abodahon, for example, and Duilin for a very short time. Those are their (would be) leaders, who even in human society are power hungry brutes (look at Napoleon, the Russian Tsars, the modern politician of today...).
Fair enough. I tend to think of them as monsters with minimal intelligence, which is what I meant by "brutes". I just can't picture too many intelligent ones in a place as hostile and unhospitible as "hell", and it has been suggested several times that the place is chaos. (Although the name is very suggestive too. Maybe it would be better to call the place "Hades" or something, so as not to confuse it with the Christian hell, etc. which DAL doesn't deal with).
"Secondly, people don't read things then suddenly unanimously agree upon it after civilized discussion." It happens, and reading a long essay is not "suddenly". I am pretty sure also that I did not say there would be no arguments (in fact I think I mentioned a discussion of the validity of the essay). In this case there were no effective counter-arguments, so the essay won the day.
Picture this: We're in hell, fire everywhere and all that rot. Then we've got a bunch of demons standing around with red skin, wings, horns, goat legs and the like.
"I do say, Beazlebubudel, that that was a very provocative and informative essay indeed!"
"Quitely so, Luciferairion! But I'm not so sure I agree with point the author makes in the second paragraph for the following reasons..."
I'm just not seeing it... (Heh...) Maybe if you played out the discussion, it would be more convinving, but I can't imagine it through that brief paragraph.
Also, I am working under the following assumptions: Demons need sustinence, they form communities, they are not that different from humans, they have the equivalents of farmers, blacksmiths, they have similar hopes for peace and a good life, and dislike oppression. I am also assuming that Hell is BIG: a whole planet for its own, almost (after all, all those dead souls...).
Fair enough again. Some backstory setting us up for this would have been really helpful though, as I pictured it totally differently. As with all places in the RP, we need description before we can visuallize it.
