Does anyone have any good suggestions on how I would write something about landscape (details of geography etc) for a planet that has been artificially made?

I'm not sure how to write the title well.. Sorry. The basis of my world is emotion and psychology, two things I'm very interested in and don't fully understand. I want to take the raw emotions, such as despair, burning hatred, and solidarity to smush them into a format I can understand better. Art. I know it may sound silly, but I really hope to achieve this one way or another. All suggestions and ideas are fully welcome, as I am at a loss.

In one of my countries, there exists a group of bug-like people who worship a god trapped inside of a tree. They hold ceremonies, obey her every command, and they never, ever leave the small city they created. There is also a high priest, who: - creates and shares visions he shared with the goddess - tries to introduce outsiders and force them to stay - holds ceremonies in her name I was wondering how to flesh out this idea more realistically, since I am pretty unknowledgeable on the religious front.

The Severance is the oldest and most disputed creation myth in the galaxy, telling how the universe began with the death of the god Serathane. Before her fall, the gods existed as thought without form in a void. When Serathane died—either by sacrifice or by murder—her body, mind, and soul became the physical laws, matter, and light that shaped reality, awakening the other gods to sensation and fear. Two main beliefs divide followers: the Doctrine of Flame sees her as a willing martyr who gave her essence to birth life, while the Doctrine of Blade claims she was slain by other gods to stop her reshaping them. Relics, factions, and prophecies all reflect these conflicting views. Whether she acted willingly or not remains unknown, and some believe Serathane will return to unmake creation. I was trying to decide between this idea or have all of the gods using their collective power to create the universe. I think I settled with this one though. Let me know your thoughts or suggestions.

The Kaosetts Heirre is are the gods reigning over a country in my world, Egeria. - They are two different entities in one body - They are the gods of Order and Chaos - Have shackled wings and a split mask, sort of like the tragedy/comedy masks - Reside in temples across the country, usually called on by priests in the area Their voices are different, kind of like ENA. I was thinking the order half would be used in major trials, while the chaos one would be there to cause change. I don't have much on the backstory or uprising of the Kaosetts Heirre, but I'd be open for ideas or change for this one!
