Kanadris is the second planet in orbit around the star Ar'Aval. It is the world of origin of the Ra'Kashan and that race's seat of power as Keepers. It is the second densest planet in the star system after Vikara, the largest of the three telluric silicate planets and the only astronomical object that currently accommodates life in this system.

Its native biodiversity has evolved over hundreds of millions of years, expanding continually except when interrupted by mass extinctions. Although scholars estimate that over 99% of all species that ever lived on the planet are extinct, Kanadris is currently hosts in excess of 12 million species.

There are approximately 5 billion Ra'Kashan who depend upon its biosphere and minerals.

The population is divided among about two hundred sovereign states which interact through diplomacy, conflict, travel, trade, and communication media.

50% of the surface is covered with water, with the remainder consisting of continents and islands that together have many lakes and other sources of water that contribute to the hydrosphere. The poles are mostly covered with ice.

The interior remains active, with a solid iron inner core, a liquid outer core that generates the magnetic field, and a thick layer of relatively solid mantle.

Kanadris gravitationally interacts with other objects in space, especially its host star, Ar'Aval and its two natural satellites, Ikalla and Eras. These moons gravitationally interact with Kanadris to produce oceanic tides, stabilize the axial tilt, and gradually slow the planet's rotation.

The axis of rotation is tilted 18.976° away from the perpendicular of its orbital plane, producing seasonal variations on the planet's surface.

During one orbit around the star, Kanadris rotates about its own axis 307 times, or one sidereal year. [1]

Name & Etymology

Kanadris, from the ancient root word ki, (-5,300 SY) a person or individual; ka the plural form, 'people', and adra, place or land. Therefore, simply, the place of the people may have been the name of a region on their homeworld in antiquity or used in general to describe the land. The same root word adra refers also to soil, although it too has many variants.

There are variants from ancient sub-cultures on every continent, including adra, land; adra'is, lands; kan'adris our lands; kol'adris the lands of our mother or vol'adris, the lands of our father. An ancient map dated to the Third Dynasty even labels the lands Voladris, the water Karas (seas or ocean), and accompanying astronomical charts Karasari (the sky, "Sea of Stars").

Since the middle of the Fourth Dynasty (-2,400 SY) this was used in its more formal form Ka'Adra'is, adra'is, The Place, or The Lands as opposed to just a place and referred to the entire world, with the addition of the kan form of ki, meaning 'we' or 'our' with familial connotations, Our Lands. Since then, like many Kashani compound words, the spoken word has drifted from its roots to the common speech and contracted from Adra'is to Adris.

In every day life most Ra'Kashan, even the nobility, will refer to their world as Kanadris, indistinguishable in its spoken form from the more formal written Kan'Adra'is.

A more contemporary term, aradra, star-lands, realms or kingdoms has been used to refer to worlds or planets in general, rather than using the more local context of adra alone. For example, when referring to the homeworld or system of another species the proper term would be aradra, as in "aradra a Terran" - the world of the Terrans, rather than "adra a Terran", the land of the Terrans; or they might simply refer to the host star genericaly, thus: ar'a Terran, or compound it entirely to araterran. They might also refer to the star by name, in this instance Kallura was its ancient name from ground-based observation, but they later adopted the Terran name for their own star, Sol.

Kanadris is orbited by two natural satellites, Ikalla and Eras as well as several hundred artificial satellites used for communication, surveillance, monitoring weather, security and other military purposes.

Observation

From the surface of Kanadris one may of course view its host star, its own two satellites Ikalla and Eras, as well as most of the other planets orbiting Ar'Aval against the fixed field of stars. Some of the host stars of the other Keepership races are visible with the unaided native eye. The brightest star in sky over Kanadris is Tirnadon at a distance of about seven light years. The closest star is Ekanal at just over four light years distant, but is relatively faint as viewed from the surface.

Sendrovis is a celestial pole star, appearing to scarcely move while the others spin around it.

Ancient cultures on Kanadris believed the sky filled with vast armies engaged in a cosmic conflict. The aberrations to the fixed stars were the moons and other planets in the Ar'Aval system. These were called lamp, or torch-bearers, carrying messages or news between armies in the sky.
