Chara is significantly similar to Aegyn in terms of properties. It's mass of 1.0871 M⊕, and the diameter of 12948 KM give it the gravity of 0.942G, which is bearable for many species. The world orbits the star of Lumina in 1.503 years, as it's orbiting 1.35 AU from the star.
Chara has a relatively safe atmospheric pressure of 1.05 Atm. The atmosphere is composed of Nitrogen, Oxygen, Helium, Carbon Dioxide, along with trace amount of other gasses. Most species from Aegyn-like worlds have trouble breathing here, as it has a lower amount of oxygen than on most Aegyn-like worlds. Thus requiring an oxygen mask to safely traverse the planet.
Chara is much cooler than Aegyn, and as such it's mostly covered by the equivalent of tundras and temperate forests. The oceans are much colder than those on Aegyn but despite that they're filled with life, mostly near the lower portions of the oceans.
Created around five billion years ago out of the stellar dust of Lumina, Chara had a violent early history, with impacts being quite common during the early years. Near the end of the more violent years, many large bodies struck the surface, creating the two moons Isis and Osiris as well as the four dwarf moons.
Life first evolved two billion years ago in the impact crater oceans that dotted the planet at the time. These life forms didn't take on a green hue as is more common, but instead took on a purple hue. As the oceans were small, many different life forms of different genetic backgrounds spread across the planet and eventually formed the incredibly complex ecology known to exist today.
Around the year 54.100 BCE, a large asteroid struck the planet causing all life to go extinct.
Chara was first discovered in 65936 CE. A starship first visited the planet in the same year, logged the system, then left. It wasn't revisited until 66324 CE, where extinct life was discovered.
Many thousands of years later, in 72592 CE, the planet came into the public eye once again when the Species Restoration Project was started. It was the most ambitious project at that time, the purpose being to restore a planet which had lost all life to its pre-destruction state.
The first signs of extinct life were massive fossils dotted around the landscape, along with destroyed remains of what once were lush forests. Scientists could recover the DNA from the fauna and flora, thus gaining information on what the planet looked like before. The planet was terraformed, its day lengthened, and native cloned life was reintroduced to the planet. Human colonists were soon to follow. The planet is today what it was before the extinction
