Analysis of information sources in references of the Wikipedia article "Sequent (MUD)" in English language version.
Most famously, as I mentioned earlier, EverQuest replicated parts of the DikuMUD codebase so closely that its programmers had to sign an affidavit swearing that they didn't include any DikuMUD code in EverQuest. I assume that also means they didn't use any code from the Sequent codebase, which was the heavily-modified DikuMUD derivative used for Sojourn MUD.
As a result, an avid DikuMUD player who had friends with visual disabilities created a modified DikuMUD called Sequent that was more accessible to people with visual and aural disabilities. Sequent improved accessibility in by creating an alternate description in each room that consisted of shorter and more direct descriptions of the world. Players could then quickly scan and participate on a more equal footing compared with their sighted peers, as the average person listens at around 150 words per minute but is able to read at around 300 words per minute.
