Tessera is a planet in the Closeness.

Adjective: Tessaran
inhabitants: Tesserans

Tessera is comparable to Earth in size, axial tilt, hours in a day, days in a year, climate, and proportion of landmass to oceans.

Tessera orbits a binary of two stars: a larger yellow dwarf called the Sovereign and a smaller red dwarf called the Tinker. The Sovereign and Tinker's rotation around their common barycenter is about 28 days.

Most of Tessera's solar insolation (i.e., warmth) comes from the Sovereign. However, during every fourth week the Tinker is partly or completely eclipsed by the Sovereign, resulting in significantly shorter days and colder temperatures--20 or more degrees Fahrenheit in some biomes. This effect is called the Chill.

Tessera has one moon called the Traveler with an orbit of 28-49 days. The Traveler has tidal effects on Tessera comparable to Luna's effects on Earth. Various conjunctions of the Sovereign, Tinker, and Traveler have significant effects on the physical and magical dimensions of Tessera.

The Chill

During every fourth week the Tinker is partly or completely eclipsed by the Sovereign, resulting in significantly shorter days and colder temperatures--20 or more degrees Fahrenheit in some biomes. The Chill has significant effects on many aspects of the flora, fauna, and civilizations of Tessera. For example, many animals and plants have more natural insulation (e.g., more or thicker fur, heat-absorbing chitin, heat-retaining sap).

History of Nations

The Shangon Empire claims to be more than one thousand years old, and some Republic states claim comparable legacies. However, it's widely believed that many other nations have existed in Tessera's history. Some legends describe world-spanning wars even greater than the Bloodstone War, as well as cataclysms such as earthquakes, volcanoes, and pandemics. In Obani history, these events mark the beginnings and ends of eras, and sometimes the births and deaths of nations.

The elven kingdom of Nok'Tur and the holy state of Sunholm have allegedly endured since at least the prior era, well before the Empire was founded. According to legend, their contemporary was the Stone Mountain Kingdoms. But a cataclysm drove the dwarves from the mountains, leaving only the Sorrows: vast, deep ruins infested by the undead and other monsters.

In the far distant past, an empire called Robrenn may have controlled much of northern Oban, perhaps in competition with a southern empire called Mardithia. Elven legends tell of a large kingdom called Tae'Sara, possibly the progenitor of Nok'Tur, and possibly part of Robrenn. Finally, there was a nation and/or place called the Carven Woods, with extraordinary magic long since lost.

Regardless of whether any legend is true, the Obani surface and subsurface are littered with the remnants of dead nations and forgotten peoples. There are remnants of roads leading only to the overgrown foundations of fallen fortresses. There are vast underground complexes that may have been bunkers, crypts, or even towns. And there are treasures and other items already found or waiting to be discovered, items of ancient origin, items both mundane and magical.
