The homeworld of my Iahonak species, Nazvet is a tidally locked world orbiting an M-class red star and it's small, brown dwarf companion. Nazvet is an old world when compared to the Earth, and it's star is entering its dying phase.

Being tidally locked, Nazvet only has one side facing the sun at all times. This side is made up mostly of scorched desert, constantly baked by the dim red sun, and has quite high winds. Further west (or east, depending) are large, arid plains of grass-like plants, where large, sunproof animals dwell. The Iahonak's original ancestors evolved here before moving to the twilight zone. The twilight area, where it is constantly at sunset, there are massive, tropical forests that enjoy heavy rainfall generated from the planet's three main oceans. This is where the Iahonak finally evolved. Even further back, the planet becomes cast in eternal shadow. The jungle gives way to cool, rocky plains with jagged outcroppings. Eventually, the plains fade away and only a snowy, lichen filled, rocky plain remains.

Nazvet only has one moon, known as Matnykoule. The moon is laced with crystalline compounds, and has a rather toxic atmosphere. No known life can exist on it.

Also, that nebula in the background is simply stylistic. There would not be any nebulae near this planet if it existed.

Interesting, very cool concept, but I don't think it would be easily livable. A tidally-locked world would have one side in perpetual darkness and freezing cold. As in "You spill your drink an it freezes before it hits the ground" cold. And the sun-ward side would be, of course, baked to a cinder.

On a planet with an atmosphere, it would be even worse. The icy-winds from the dark side mingling with boiling air from the light side would breed thunderstorms and hurricanes the likes of which we can only imagine. Permanent superstorms and hail seems like a less than ideal situation for life to exist.

Now... if this softer scifi, you *might* be able to get away with making the moon much larger and closer, and having it orbit almost perfectly on the plane of the ecliptic. It would block enough sunlight on the day side, and it's crystalline surface would reflect enough on the night side that it would partially even our the thermal variances. (mind you, I just came up with this idea, and haven't done any math to confirm if it's probable or even possible, but I didn't want to rip into your idea without at least trying to present a solution that lets you keep as much as possible.)

Actually, they wouldn't be entirely unlivable. Adaptations would just be zone dependent. The Iahnoak are adapted mostly for the bright side of the middle zone, but they have moved across the planet, building cities mostly on the darker side. Animals on the bright side would be adapted for scorching temperatures and bright light, while creatures that could live on the dark side would be adapted for eternal night and cold.

There are large storms along the twilight zone, but hurricanes cannot reach far enough inland to damage the larger rainforests and jungles. Plus, the constant sunlight on one side, where it is still cool enough for life to exist, would cause jungles to flourish. But the storms aren't permanent. They would be common, but not permanent. And judging by the way life flourished on a planet originally filled with similar storms (Earth was originally heavily ocean covered, and would have had far more massive storms than we have today), I'd say macroscopic life could live on many weird environments. The Iahonak of course, would not build cities near those areas due to the storms. River ports could be common, though.

Moon reflection could probably help the dark side a little. It is permanently below zero, though, especially at its darkest point. Most of the life in it consists of lichens and little more. The bright side has more macroscopic organisms.
