Who Is W. D. Gaster?
W. D. Gaster is a hidden figure referenced through rare events and inaccessible game content in Undertale. The strongest direct Wingdings association comes from room_gaster, where ENTRY NUMBER SEVENTEEN is displayed in uppercase Wingdings. The room is not reachable during normal gameplay; it is accessed through SAVE manipulation or debug methods.
How Gaster's Wingdings Works
There is no separate Gaster grammar or vocabulary to decode. ENTRY NUMBER SEVENTEEN is ordinary uppercase English displayed with the Wingdings typeface. That is why uppercase matters when recreating its style. The portable symbols on this site are Unicode equivalents for browser compatibility and are not the proprietary Wingdings font file.
ENTRY NUMBER SEVENTEEN
The hidden entry begins with “ENTRY NUMBER SEVENTEEN” and moves into the repeated phrase “DARK DARKER YET DARKER”. Later it describes negative photon readings and an experiment that appears increasingly interesting, ending by asking two unnamed listeners what they think.
This is useful for decoding because the source is explicitly all caps and rendered in Wingdings. Rather than reproducing the whole game passage here, use those verified phrases as test strings in the translator above.
Gaster vs Regular Wingdings
The character set is not a special Gaster alphabet. The distinction is context: Undertale uses uppercase Wingdings for this hidden entry. A general Wingdings converter may accept mixed case, while a Gaster-style recreation should default to uppercase if it aims to resemble ENTRY NUMBER SEVENTEEN.
Where the Wingdings Appears In-Game
The relevant text is found in the inaccessible room_gaster (room 264 in most versions). It follows the True Lab generator room in sequential room order. When the message finishes, the screen briefly goes black and the game closes. This material is hidden content rather than dialogue encountered in an ordinary playthrough.
Frequently Asked Questions
What is Gaster's language in Undertale?
Gaster is strongly associated with Wingdings. The hidden ENTRY NUMBER SEVENTEEN in room_gaster is displayed in uppercase Wingdings.
Is Gaster's text real Wingdings?
ENTRY NUMBER SEVENTEEN uses the Wingdings typeface. It is not a separate fictional language with its own grammar.
Can I write my own name in Gaster's language?
Yes. Type your name in uppercase to imitate the convention used by ENTRY NUMBER SEVENTEEN. This site's output uses portable Unicode equivalents rather than the proprietary font itself.
Why do Gaster symbols look like emoji on mobile?
Portable Unicode symbols can receive emoji-style rendering on phones. Undertale's original text uses a font, so its appearance is not identical to portable web symbols.
Does this work for Deltarune too?
This page is specifically about the Wingdings material associated with Gaster and Undertale. Deltarune has related mysteries and allusions, but they should not be treated as a single confirmed Gaster cipher.
