The words belong to W.D. Gaster, the mysterious former royal scientist whose story is only hinted at in Undertale, and Entry Number 17 is one of the fragments fans have pieced together from the game's hidden material. Because Gaster himself never appears clearly in the main story, the entry has become a touchstone for lore hunters, spreading through fan readings, theory videos and soundboards shared across the Undertale and Deltarune communities. Its unfinished, questioning ending keeps it popular, since it invites speculation about Gaster, the darkness and the two people he addresses.
