The beating Heart of Celtara.
Born in the turmoil after the Great War, Haven quickly grew into the largest city in the world. Every sixth person in the world lives on this giant island in an endless forest made of concrete, steel and glass. Day and night large fleets of freighters and tankers fuel the cities hunger for resources and deliver manufactured goods into the rest of the world.
Wealth and prosperity differ greatly over the island. Old Haven in the north houses most of the poor and is in reality ruled by various criminal gangs and organisations. New Haven further south has proper standards, clean streets and is ruled by proper criminals, in suits. The southern edge of island The Spire is the playground of the super rich and terminally bored. Cascading waterfalls, glass towers, domed jungles are the least eccentric things you will find here.
Lastly, The Outland the most northern part of the island is under the control of warlords who rule with an iron fist. Separated and yet connected to Haven this is a different world with different rules.

If you are looking for a traditional cyberpunk setting then you will find it here. Haven is so massive you could spent your whole life walking its streets and never walk the same twice. In its depths you will find individual communities, conflicts between criminal organisations, power struggles of mega corps and the deadly games of politics.
It is a tough turf, it will demand from you and your group to make hard decisions and to take sides. If you want to make it in Haven you will have to spill blood, just make sure it is not your own.
Still, if you look close enough you will find a lot of good here too. Hope and progress, colorful markets, hidden gardens and truly good people. It takes a special kind of person to protect all of this. Sometimes that is a honest cop, sometimes a crime lord who cares about the community and sometimes a group of mercs who would rather see a smile than big pile of cash.
