So what's the "big picture" and story of everyone's megadungeons? Do you have one yet, or are you just adding rooms and building things up slowly? What sorts of factions (if any) are the major players?
Mine will be the lost city of Kyrthar Tahlketh. A thousand years ago the city was overrun by demons and devils, so a sorcerer sealed it and trapped everything that was inside. So for factions we have:
• The new demon and devil Lords who rule over their new kingdom, that nobody, even themselves, can't leave. Even the souls are trapped inside. There is a lot of onfig6betqeet the two sub-factions:
○ The Demons
§ The Cult of the Unbroken Circle: This faction is made up of a group of sorcerers who practice dark magic and worship ancient demons. They seek to break the seal and unleash their demonic masters upon the world.
○ And the Devils.
• The humanoid slaves. The descendents of the citizens of the city.
• The collaborators: humanoid descendents, while slaves themselves, have a higher status who keep the other slaves in check.
• The ghostly Court: the Ghosts and Spirits of the Royal Court of the Kyrtharian Empire, who one day hope to rise to power again. Living in the haunted Palace, on of the few places in the city outside of the controll of the Demon-Devil Lords
• The Guardians: mechanical and magical beings, that were created by the Kyrtharian Empire to protect the city from invaders, most were destroyed during the initial stages of the invasion, but some remained. They are quite inflexible and can't leave the areas they protect, but that areas are Demon and Devil Free.
• Mutants: Descendents of Citizens and Demons, who were warped by the magical warfare. They are solitary, unstable and unpredictable, getting chunned or killed on sight, when possible, by most other factions.
• The resistance: a group of descendents of the inhabitants of the city who consists of freed slaves, who are fighting the demon overlords and trying to break their power. Secretly they are lead by a devil, who lost a power struggle against other demons and devils.
• The forgotten: Freed slaves, who hide in the ruins and stay in protected areas, that don't have the desire to fight the devils and demons. They are wary of outsiders and will only work with adventurers if they are convinced that doing so will benefit their own survival.
• Scavangers: similiar to the forgotten, but they prey on everything they think is weaker then them.
• The Cult of the Sealed One: This faction reveres the sorcerer who sealed the city and views them as a divine figure. They believe that the seal must never be broken, and they work to prevent anyone from attempting to break it.
• The Enclave: This faction is made up of a small group of individuals who were not originally from the city but found themselves trapped inside it when the seal was activated. They have managed to carve out a relatively safe haven for themselves and have become quite self-sufficient, but they are always on guard against attacks from the demon and devil lords.
• The Glimmering Collective: This faction is composed of mutants who have developed strange powers or abilities as a result of exposure to the magical energies of the city. They have banded together for protection and to share knowledge of their abilities, but they are often shunned by other factions because of their strange appearance and unpredictable nature.
• Some powerful individuals:
○ The mage Kenza Icesoul: a powerful mage who was trapped inside the city when it was sealed and survived. She could hide from the devils and demons and uses the situation to continue her inhuman experiments, now without any form of proper oversight. Even the demons and devils avoid her.
○ The Keeper: A humanoid who has taken it upon themselves to guard a valuable artifact or location within the city. They are fiercely protective of their charge and will stop at nothing to prevent it from falling into the wrong hands.
○ The Trickster: A mischievous and unpredictable imp who enjoys causing chaos and confusion. He may be willing to assist the adventurers if it suits his own purposes, but he cannot be trusted.
○ The Collector: A devil who has a penchant for collecting rare and valuable items. He may be willing to trade with the adventurers, but his prices are steep and his loyalty is always questionable.
○ The Prophet: A humanoid who has visions of the future, including the possible end of the seal that binds the city. He is gathering a following among the slaves and freed people.
Factions outside the sealed city:
• The City of Freehaven
• Rival adventurers group and the patrons who hired them
• The academy: the patron of the adventurerers group
• The Gnoll Tribes: native tribes in the area around the sealed city
Thats so far all I have in the Faction front.
