Purpura is a E-Class terrestrial planet in the Rubrum system, and is home to a variety of sea creatures, (such as the Uident) and some amphibious land creatures. It is the second planet in the system, has 3 asteroid moons, and has a temperature of -16.2 degrees C. It's atmosphere is almost entirely CO2, with some O2, and has an atmospheric pressure of 0.651 atm. It has a diameter of 6621 km, making it around half the size of earth and with a gravity of 0.49 g. It has a rotational period of a slow 7.510 days, and a solar day of 22.529 days.
The surface of Purpura is primarily purple and magenta rock, with a few oceans and inland seas. There are river systems and lakes that flow through the planets, which are a sort of icy slush flow. There are also lots of volcanoes that dot the surface, some active but most are dormat. The volcanoes could have been a source of life, as they are a hotspot and spew out many helpful minerals. There are ice caps near the polar regions.
The life on Purpura is more then basic, but still not as intelligent as humans. There are some small bushes, mosses, and grasses near the coastal areas on land, but it is too cold for larger tree life. Only a few small insects and amphibians have evolved to go onto land for food. However, there is lots of life in the oceans. Due to the active mantle, there are many hydrovolcanic vents near the ocean floor, which are teaming with life. They all range from single celled organisms, to creatures the size of whales. In the depths, almost all the flora and fauna are bioluminescent, and produce a beautiful purple-magenta glow. Sometimes glowing bacteria from the depths wash up on the shore and make it glow! The most advanced life there are the Uident, a dolphin-like species which are very social. They are nearly intelligent as early humans, but lack the skills to build houses, spaceships, etc. They communicate with a variety of whistles and squeaks, and have their own names and tribal systems. They normally hunt the depths for small crabs and other sea life, and hardly ever go to the surface because it is so cold. They have evolved gills to breath underwater, so going to the surface is futile.
