Kepler’s Logistics

Time & Calendar

Kepler operates on a 24-hour day and a 372-day year. The calendar is divided into twelve months, each containing exactly 31 days.

Global Time Zones

Kepler’s immense geographic scale places its civilizations across multiple time zones. Salvation Island, located near the center of the known world, serves as the global reference point at +0. Most of the Ten Great Sovereigns span multiple time zones rather than existing entirely within a single zone.

Sovereign Time Zones Range
Kanata 1 +0
Holy Metzia 2 0 to -3
Hordad 3 +8 to +10
Atteria 3 -1 to -5
Teranua 4 +1 to +5
Eiria 5 +0 to -6
Sang 5 +4 to +10
Jureslavia 6 +1 to +8
Delsur 7 -2 to -9
Uttaria 9 -2 to -12
Global Reference
Salvation Island is positioned near +0, close to the geographical center of the known world. It serves as the primary reference point for Kepler’s global time system and is approximately two hours ahead of Capril.
Sunrise
Because of Kepler’s immense west-east scale, sunrise occurs at substantially different times across the Great Sovereigns. Uttaria and Delsur extend into the easternmost time zones and are among the last regions of the recognized world to experience sunrise, while their western territories experience sunrise significantly earlier.

Annual Cycle

Kepler’s year is divided into four periods. Each period lasts 93 days, or three 31-day months.

Planetary Scale

Kepler is a massive planet, possessing the surface area of approximately one-and-a-half times a conventional human-habitable world. Approximately 60% of its surface is covered by water and 40% by land.

Estimated Global Surface Area ~295.5 million sq. miles
Ocean Area ~177.3 million sq. miles
Land Area ~118.2 million sq. miles
Water / Land Ratio 60% / 40%

Planetary Travel

The scale of Kepler can be measured against the theoretical time required for a signal or physical phenomenon to travel once around the planet.

Speed of Light
~0.22 seconds
Approximate time to travel once around Kepler.
Speed of Sound
~48.7 hours
Through dry air at approximately standard conditions.
Note: Travel-time estimates use Kepler’s equatorial circumference and standard atmospheric conditions for the relevant zone. Values are approximate and vary by latitude, altitude, and seasonal atmospheric density.

Global ID Classifications

⚫️ Black ID

Issued To: President and Vice President of the World Council

Privileges:

  • Access to any location at any time.
🟢 Green ID

Issued By: World Council

Issued To: World Council officials, C-BAR soldiers, and categorized Great Wanderers

Notes:

  • Great Wanderers are recognized as Green ID holders in most nations, though they never formally accepted it.
  • Allows entry into all sovereign nations and recognized states, with approval/clearance dependent on each specific state.
  • Permits access past the 50th Strata of the underground labyrinths.
🟡 Yellow ID

Issued By: Each Sovereign Nation/Recognized State

Design: Includes the flag, crest, or insignia of the state

Information Included:

  • Basic traveler and personal information.
  • Open slots for approvals from other sovereign nations and recognized states.

Requirements:

  • Individual must meet travel prerequisites and laws to apply for travel approval to other sovereign nations/territories.

Restrictions:

  • Generally prohibited from crossing Strata 50 of the underground labyrinths for safety reasons.
🔴 Red ID

Issued By: World Council

Issued To: Individuals banned internationally, even from their own country

Notes:

  • A sovereign nation can revoke someone’s Yellow ID or prosecute them, but this does not automatically make them Red ID status.
⚪️ White ID

Status: Individuals who are stateless or whose Yellow ID/citizenship has been revoked, but have not gained legitimacy elsewhere.

  • Not formally issued; flagged as non-listed in the global database by nations.
  • Restrictions are reputation-based; if a Great Wanderer declares statelessness, they still retain their Green ID status.
  • Many White ID holders end up in straggler territories or dwelling in underground labyrinths. They are nomads and unknown wanderers and explorers for the most part.
