So today I've thought of a fun campaign world for a potential adventuring party to explore and discover
The main premese of this campaign is that the world has just exited a calacysmic event that has rocked the world to it's core that left only one truly great city standing called the last Bastion of hope. This city has large towers walls and different layers and while it now does trade with other cities it can also be completely self sustained. In today's time the city is the capital of Bastinion a new empire that seeks to reclaim the lands lost to civilization to the blood war cataclysm

section two the blood war cataclysm 
this universe has a blood war in it and the blood war at one point managed to spill heavily into the material plain causing mass devistation. The cataclysm started when a large demonic portal opened on the material plane. At first thought to be an ordinary demonic opening a horrible truth was soon revealed. This was an attack set up by Orcus who had managed to get his hands on a powerful item. The demonic amulet of the demegorgen giving him control of the great beast. The devils unable to abed by this attack send forces into the material plane  throught devil opened portals. Turning it into a prime place for the blood wars to spread across the lands. Orcus's cults grew in power with the attacks and so did devilish cults allowing them to cause even more destruction in there cities either leading to entire lands down falls or attacks by the opposing armies. the gods wanted to end this event as soon as possible and send one of there selfs down to deal with the event. However the god made a great mistake in underestimating the power of his opponents and despite dealing heavy casualties was eventually defeated and brought to his knees and to be slain. His power was consumed by both of the strongest leaders in the war. Both Asmodeous and Orcus gained incredible god like powers allowing them to rain down with even more power causing even more distruction. The other gods tried to intervene but where fearful for they could only side with Asmodous and siding with him would give the archdevil to much power. They decided to play there cards right and wait for the time being as the war continued to spread across the material plain soon only leaving a few cities remaining. Eventually these few cities banded together and powerful order of adventures rised up to the challenge of the cataclysm. They where called the the order of civilzation. Within there ranks many rose to titles of promency and heroism (despite some morally flawed people) and they moved swifted to push back the devils and the demons. This adventuring order managed to gain enough traction that the gods throught there lot in with them to help save the Material plane. Eventually the order managed to fully drive out the devils from the material plane leaving Asmodous to continue his sceams as he now had new powers making his position of leader of hell only more secure but hell had suffered many losses from there lack of defense of the home plain as other demon lords had attacked the nine hells. Only the chaotic hoards of demons now remained. However a trajecty struck the adventures as they leader was slain by the demogorden and was given new life by Orcus as an incredibly powerful undead that had a small divine spark in it giving it incredible powers. This combined with a loss of leadership forced the order of adventures back and more cities where destroyed eventually only leaving Bastinion which began to prepare itself for the worst. However the gods had different plans and together they sculped a champion. A perfect holy warrior with a powerful divine spark how was named Balagan. Balagan was incredibly powerful and partically immortal and became the new leader of the order of civilization. With Balagan in play the order managed to push back leading to a final conflict in the fields of corrupted land. As the two final forces made there way to fight they managed to defeat the demogorgen sending him away. Eventually the conflict came to a head as a powerful god managed to banish orcus back to the abyss with the aid of a powerful half elven cleric Lisinia who was nearly slain in the process leaving her gravely wounded. The two most powerful forces on the field then began to do battle with each other as the great Orcus undead did battle with the divine made warrior Balagan. Neither of them could best the other and there battle alone caused many permate casualties as there blows gave out a soul destroying power. Eventually Balagan used his powers to forge a demiplane both of the creators became banished to where they continue there enternal conflict and thus the demons had been finally pushed back from the material plane. However the lands of the material plane where forever scared as only one truly great city stood alone amist the destruction. Several lone devils and demons still travel around the land and many places remain guarded by eternal watch men who will never leave as they do not understand the war has left the material plane 

100 years later. After 100 years the old has actually began to heal. While no where near what it once was smaller towns could now finally emerge and the great last city was no longer the only city remaining. However being the only power left it seeks to make the world it's empire by rebuilding the world around the Bastion City
currently the bastion city is the Capital of Bastinion and it is lead by the frail old half elf Lisinia who managed to banish Orcus into the abyss once again. She has a long scar down her face and is no longer the beautiful women she once was. She is frail and can feel her powers slipping away as she reaches deaths door. While she wants the new empire to be a good one others disagree
the city is very lawful and follows a strict moral code that has only recently began to let up. Currently poverty has become a semi issue but many people in the city live safely. Even if sometimes under an iron fist. Also the worship of any demons or devils is not allowed and often worshippers are simply executed 
Factions of power
because cities need factions here are the major factions of the bastion city
-The higher order. The higher order is the monarchy that runs the bastion city. it is lead by Lisinia who has several advisers from the old order who still live. The strongest in power of them is the wizard Vestin. An elf who wants to see a long and prosperse empire but cares little for how it is truly done leading him more down the path of neutrality. The other proment members of the higher order are the dwarf paladin Vergen who follows a strike moral code and wants to rule with an iron fist and keep the current legal code with a few changes. Finally Ossen a halfing bard who is often the moderate voice using his charisma to help calm down the other two members of the higher order
-the civilized. The sort of noble class of the bastion city. The adventures who survive the cataclysm where rewarded with a status like nobility. While the position is losely defined they are often favored by the guards in debates and some are members of the order of defense. there views vary a lot some content to simply settle down where other continue to rise to the challenge of fixing the world even after defending it 
-the order of defense is what makes up the guards and law portion of the city. They are lead by the son of Regendal a fighter for the order of civilization named Relant. Relant is only half the man his father was and feels he needs to prove himself. And while he can be a bit brute headed at times he often works towards his goal and often does not act foolishly or rash even if his solutions are simple. While the order of defense works hard to stomp out corruption a bit still reamins in there ranks 
-The merconess. The merconess are the merchants of the city who during the Catacysm became incredibly wealthy and connected to many of the different adventures who know hold onto noble positions. They have made there own guild connecting them all together and while compition exists regulary the merconess work to make sure it never goes to far
-Vestin's loyal. this guild is a guild of many powerful mages some of who worked for or in the order of civilization. even if they didn't fight in battles there magic was very important. the group is now a guild run by the elven wizard which only increases his incredible power in the council
-minor thieves guilds. There are small black markets and theives guilds working within the city against the law however many are weak and crushed easily by the order of defense. but rumor has it there is a powerful group growing
-the order of the uncivilized. A group over the past years has emerged to oppose the bastion's city rule. While on the surface they are a legal group working to protect the right of the people deep down they are a revolution planning to have a coup of the government when Lisinia eventually croaks. Despite the fact many (even within this group) respect her her death will set things into motion for them and as she become older and more frail the group tries to gain even more power. 
-the order of new. A new adventuring guild that both Vergan and Ossen co run along with there regular powers. The two older adventures often have arguements about how the guild should be run. Despite that however the two are often considered friends. This guild is recruiting new age adventures who will be willing to adventure into a world left in ruins by the war they once fought in
adventure hooks:well currenly the world is in drastic need of more and new adventures as many of the old order's adventures have passed the world needs more
current hooks
-the adventures are highed as a group that will explore the demonic waste lands and see what areas civilzation could exist
-toom raiders. the untaimed wastes offer a vast chance for wealth and glory along with paraless danger
-fighting the order of the uncivilized. While still innocent in public eye and even posessing some support the current government sees the threat they pose and are hiring private adventuring groups to explore


so here's the huge list of things I've made for this crazy world. I'm looking for ideas to help revise and polish what I currently have and also feel free to give me some ideas of things you'd like to see in this demonic waste land or of wacky poltical figures I'm all ears to working on this idea
