alltmera

Alltmera is a fictional planet featured in the science fiction novel "The Expanse" by James S. A. Corey. It is the third planet in the Sol system, orbiting between Earth and Mars. Alltmera is a water world, with a global ocean covering approximately 70% of its surface. The planet is known for its diverse marine life and unique geological features, including massive underwater volcanoes and hydrothermal vents.

The planet's ocean is home to a variety of sentient and non-sentient species, including the Alltmerans, a humanoid species adapted to aquatic life. Alltmerans have evolved to breathe underwater and possess gills, as well as webbed hands and feet. They have a symbiotic relationship with the planet's marine life, using their advanced technology to communicate and coexist with the various species that inhabit Alltmera's oceans.

Alltmera's surface is composed of vast continents and islands, with a thin layer of atmosphere that supports a limited amount of plant life. The planet's climate is relatively stable, with temperatures ranging from 0 to 30 degrees Celsius. Alltmera's unique environment has made it a valuable resource for the exploration and study of extraterrestrial life, as well as a potential site for future human colonization.

The planet's name, Alltmera, is derived from the Latin word "altus," meaning "high," and the Greek word "meris," meaning "sea." This reflects the planet's status as a water world and its significance in the Sol system. Alltmera plays a crucial role in the novel's plot, serving as a hub for interstellar trade and a source of conflict between various factions.
