worlds by category

A world is a planet, often understood as a planet either inhabited or visited by humans. Most of all known planets are not commonly called worlds, as humans have never approached even their star systems, much less any of the planets.
An inhabitation is the permanent settlement of a world by humans.

Inhabited worlds with doors

• Syrdarya 2122/2125
• Tunguska 2123/2124
• Nithon 2123/2123
• Weeper's Pit 2124/2370
• Horwols 2125/2126 - site of pre-human ruins, suggesting people moved off-planet
• Wayn's Rose 2127/2127 - Wayn herself moved here and died here; site of pre-human ruins and psychics
• Jasminia 2129/2137
• Eldrachs 2129/2142
• Woont Moroos 2129/2133
• Izmat 2130/2130 - "The New Earth"
• The Flare 2133/--- - a burning world, cause of a great disaster, cause of pause
• The World of Death 2140/--- - another disaster, another pause
• Vormahault 2149/2149 - colonized by self-exiled adventurers
• Ichacrane 2149/2152 - colonized through sub-tunneling from Vormahault; a sea world over an alien seafloor civilization of Industrial Age type

Next century, thru Izmat:

• Ellisvere 2200/2205
• Orchamon 2201/2222
• Juddrafordamoon 2201/2230
• Incha's World 2202/2254
• Guudrun 2203/2232
• Hollix 2204/2295
• Neyd Gara 2204/2311 - Earth's Opener also contacted Neyd Gara a month after Izmat did
• Lafahey 2205/2278

In reaction, Earth restarted its own, leading to five more discoveries.

• Draman 2200/2203--2267,2354
• Colichs 2200/2202
• Xuta 2200/2205
• Feyda 2202/2202
• Bocolico 2203/2205

Inhabited worlds without doors

In star systems with a door, it is not practicable to have doors between the various planets and other locations. Thus slower, mechanical propulsion is necessary. The following worlds are in same star systems as some other world with a door in it. They are commonly called sisters of their door-having worlds.

• Mars
• Izmat II 2132/2133 - a less amenable planet in Izmat system; had a door from Earth
• Jasminia IV, whose third moon (Jasminia IVc) is home to the Artists, a Stone Age alien species. Jasminia IV is a sister of Jasminia I.

Visited worlds

These worlds were never permanently inhabited. From Earth:

• The Husk 2122/---
• Corpseland 2124/---
• Nowhere 2124/---
• Blastoff 2124/---
• Black Death 2124/---

From Izmat:

• Taint 2202/---
• Disappointment 2203/---

There should be more of these from the latter days, too.

Unvisited worlds

Without doors, travel from one star system to another is so slow as to be practically impossible; it has never been done by humans. For this reason, though some intriguing worlds have been observed from nearby inhabited or visited ones, they have for the lack of a door not been visited.
