Found mainly in fantasy settings, this trope is about fictional scripts invented by the author. Sometimes, they are used as a fancy substitute for the letters in the work's original language, at other times, they come along with an entire Constructed Language/Fictionary.
- A parallel alphabet exists in Disney's Atlantis: The Lost Empire. In fact, Milo Thatch deduces that no further evidence of Atlantis has ever been found because one glyph was mistaken for an "R", leading searchers to Ireland in vain. The glyph is rightly a "C", because Viking raiders routinely made port in Iceland, near the dormant fumarole which is the access point to Atlantis.note
- The Klingons in Star Trek have their own language as well as a writing system◊.
- Circular Gallifreyan is the writing of Time Lords in Doctor Who.
- Babylon 5. The Minbari language◊ is used a number of times throughout the show. In one case they have a small joke; Vir is sent to be ambassador on Minbar and shows up later wearing a ceremonial welcoming robe which says on the front in Minbari writing "Aloha."
- The Ancient language in Stargate has a whole alternative alphabet. Why they had characters for 8 and 9 when their mathematics was supposed to use base 8 is unknown.
- Adherents of various beliefs in Hermetic Magic created several "magical" or "angelic" scripts, such as the Theban script of Tritemius, the Alphabet of the Magi by Paracelsus and the Enochian script (and language!) by John Dee and Edward Kelly. Many of these scripts mimic the structure of the Hebrew script and are meant to write Hebrew words.
- The Ultima series had the default Runic, Gargish, and Ophidian Alphabets. Its Spiritual Successor, the Shroud of the Avatar series has its own artificial runic script, as well.
- The Elder Scrolls series has the Daedric Alphabet, the Dragon Alphabet, the Dwemer Alphabet, the Falmer Alphabet, and they yet-untranslated Elder Alphabet.
- The Thief series has the Keeper Glyphs of the Order of the Keepers. Public signs in the third game also hints at the world of the series using a different script to any real world one, even though all in-game texts and readables are rendered in Latin scrip to the reader.
- In The Legend of Zelda: The Wind Waker the Hylian language appears in text as a Artificial Script. In the second playthrough, Link can comprehend the Hylian language, or it becomes legible to the player at the very least. Or you can take the time to translate them yourself. The Legend of Zelda: Twilight Princess and The Legend of Zelda: Skyward Sword also have their own Hylian scripts, while The Legend of Zelda: Breath of the Wild has an Ancient Sheikah script.
- Not an alphabet, but in Riven, you have to learn the base-25 D'ni numerals to solve some puzzles.
- The Ancient Language in Fire Emblem Tellius, spoken mostly by the Heron tribe, which uses a highly stylized writing. It's actually English in a font that's so fancy as to be unrecognizable. Translations can be found here and here.
- Commander Keen has an alien script but if you can translate it, the words are in English.
- Many Final Fantasy games have artificial scripts for the in-game languages, sometimes more than one in the same game. They tend to be substitution cyphers for English. Details can be found on the Final Fantasy wiki.
- For the various comics set in Overside, Evan Dahm created a number of different scripts and alphabets for the different societies. Some of them are just scribbles, but others are fully functional writing systems, such as Seen Script (from Rice Boy), Machine Script (mainly used in Order of Tales), and Sahta Script (from Vattu).
- In Paranatural, several ghosts and spirits speak in a script that's actually a modified Latin alphabet. Each letter is a rough trace of the negative space in the corresponding Latin letter, then the whole sentence is rotated 90 degrees.
- Futurama has an alien script which the writers threw in to amuse and bewilder their audience, but the script was solved fairly quickly. So they made up another whole alien script.
