Gazetteer – Hollow World

Overview of the Hollow World

What is the Hollow World. It is a preserve of cultures from the outside world frozen in time. Details about this places is scare and more rumour than facts exist. Something about the information is illusive and seems to slip away over time.

This region is protected by the Immortals, and mortals are playing by different rules when they tread in the domains not their own.

There is a world within the world. The Sun never moves… Always up at the centre of the sky, colour of blood. Surrounded by floating islands (planetoids) which provide time calculations based on their orbit. (Currently beyond the characters adventuring here)

The planet of the Known World is not a solid ball like our Earth is. In fact, it’s hollow. A tiny sun hangs in the centre of the hollow, and vast polar openings permit travel between the inner and outer worlds. The interior landscape is called the “Hollow World,” a place of ancient mystery.

The polar openings leading into the Hollow World are so huge that their curvature is very, very gradual. That, combined with the fact that these regions are perpetually shrouded in fog, means that people can travel from the outer world to the inner (or vice-versa) without being aware of it.

The interior sun sheds daylight at all times in the Hollow World; night never falls, and creatures susceptible to sunlight (such as vampires) are rare indeed.

The interior world has long been hidden from the outer world-the few outer-world explorers who have found it have either died there, stayed there willingly, or returned without publicising their discovery. To this day, the existence of the Hollow World is not generally known in the outer world.

The Hollow World is home to monsters, animal species and cultures that have long vanished from the outer world. Every prehistoric animal species listed in the Monster Manual is common in the Hollow World. Here, too, are nations that are ancestors of many of the outer world’s cultures.

The Hollow World was set up by the Immortals of the Known World. Their influence has kept the cultures they have planted here virtually unchanged; each culture remains frozen at the cultural and technological level it had attained just prior to being brought here.

The map shows several nations of the Hollow World, all of which lie on the great continent of Icitia.

Important Note: On maps of the Hollow World, the directions of East and West are reversed, an effect of its unique configuration. Therefore, if North is at the top, then West is to the right and East is to the left in the Hollow World.

Magic is Different in the Hollow World

Effects on magic discovered to date:

  • Abjuration: The numerical effect appears to be doubled in examples used.
  • Conjuration: Summoning in creatures does not work. Dimensional movement and access does not work. Creating something from nothing does not work. Enhancing what is there appears to work.
  • Divination: Detection and Communication spells do not work. 
  • Enchantment: Charms, Compulsions and Holding spells do not work.
  • Evocation: energy attacks are unknown and require a skill check to cast. 
  • Illusion: Are only half as effecting, the DC to see through an illusion is halved, the numerical effects appear to be halved as well.
  • Necromancy: Unknown at this time.
  • Transmutation: Changing the shape of one thing to another does not work. Enhancing things have a limited effect. Returning things to their natural state seems to work.
  • Rituals: Mostly work with a limited version.

Skill checks to cast unknown spells: is DC 15 + Spell level with failure having the spell fail and disappear from your known spells, and a roll of 1 removes it from your spell list, spell book and ritual books.

  • Arcana check for Sorcerer’s and Wizards
  • Religion check for Clerics and Paladins
  • Nature check for Druids and Rangers
  • History check for Bards and Warlocks

You cannot learn a new spell unless it comes from a Spellbook, Prayerbook or Craftbook due to the nature of the setting you don’t receive any spell at new levels unless your teacher provides it.

Artefacts have different rules:

  • Channelling magic through an artefact using up some of its power, but also allows the subversion of certain types of magics. Spellcasting roll DC is 10 + level of spell being cast.
  • Enchantments seem to work with a spellcasting roll.

The Power of Culture Compels Us


  • Construction and items part of the culture of the lands will have their hardness doubled and don’t seem to see the ravages of time.
  • Construction and items not part of the culture of the lands are not structurally sound and has no hardness rating and seem to deteriorate at a rapid speed. (loose 5% of its hit points every 24 hrs)


  • A native always have advantage on rolls when dealing with another culture in their cultural territory.
  • Anyone not of the culture in the cultural lands have disadvantage against people of that culture.
  • Anyone wearing weapons, armour, gear or clothing of a culture other than their own or the local culture have disadvantage vs those of the culture while doing so.
  • Local people have resistance to all damage. This eventually upgrades to immunity to damage  and ageing depending on numerical chance of cultural survival.
  • A non-native feels restless and a need to travel if they stay more than a few days in any areas belonging to a native.
  • A native feels a need to settle and raise a family, can be content not to move beyond the sight of their homes.

Ritual of cleansing and connecting – There is a ritual to be accepted into the culture and become one with the people. Doing so removes all items, memories and skills from beyond the lands you have chosen as your own. Over time you become one of the natives.

Ritual of separation and leaving – This is a ritual of severing a individual from the lands. This is normally done to criminals, removing the protection of the lands for the duration of their penance, This can be done by request as some natives are at heart explorers and wish to see more than their home. You loose the connection to the culture and are no longer a native.
