AdventureWriter

The Quill (formally known as The Quill Adventure System) is a program to write home computer adventure games. Written by Graeme Yeandle, it was published on the ZX Spectrum by Gilsoft in December 1983.[1] Although available to the general public, it was used by several games companies to create best-selling titles; over 450 commercially published titles for the ZX Spectrum were written using The Quill.
