Obsidian Alien Planet Name Generator
By Harper Lockhart · March 22, 2026 · Sci-Fi & Tech GeneratorsFans of fantasy franchises know the feeling: the lore is rich, the map is drawn, and the alien planet is still nameless next to a polished candidate like Cyus. Instead of scrolling lists that repeat the same ten entries, you get fresh combinations every press — this batch alone produced Cyus, Nyxprime and Dexprime.
Building Blocks: Prefixes, Cores and Endings
If a generated name feels like a mouthful, drop the middle syllable; Cyus trims down fine and keeps its character. The generator leans on that pattern. It pairs hard openers with flowing endings so a result like Cyus reads naturally in dialogue. Names like Cyus or Nyxprime follow the classic two-beat rhythm that makes a name easy to shout across a tabletop. Longer builds such as Cyus give a formal, almost ceremonial feel, while clipped forms like Nyxprime read as informal or youthful.

Common Naming Mistakes to Sidestep
Numbers stuffed into the middle of a fantasy name. If the setting has no digits in its lore, even a good build like Cyus breaks immersion. Names longer than four syllables for characters who talk a lot. Your players will abbreviate Cyus anyway, so choose something that abbreviates well. Copying a trademarked name with one letter swapped. It reads as derivative next to an honest original like Cyus, and it invites takedowns.
Where These Names Earn Their Keep
Tabletop players burn through these fastest: an one-shot needs an alien planet tonight, and nobody wants to workshop names mid-session. Fiction writers use the reroll button as an idea pump — generate ten, keep the two that spark, and let a discard like Cyus name the sequel’s cast. Even casual users grab a batch for email handles, pets, or a private joke — Cyus has probably named somebody’s cat by now.
Field Notes Before You Generate
Change the style tab before changing anything else. Each tab shifts the syllable balance more than any single reroll — compare Cyus under one tab and Nyxprime under another. Keep a shortlist. Names like Cyus that survive a second read the next morning are usually the ones worth keeping. Add a keyword first. The generator weaves it into some results, anchoring the batch to your story instead of handing you another Cyus.
Tip: a keyword anchors the whole batch to your story.

What an Alien Planet Name Says Before You Do
In most settings an alien planet name does more than identify — it announces origin, rank, and temperament in two syllables. If your alien planet belongs to a faction, borrow that faction’s favorite endings; a family of names like Cyus and Nyxprime reads as one people. Game masters can use this: give the innkeeper a soft name and the mercenary a clipped one like Cyus, and players will read the room instantly.
