Very interesting. Do you remember which source you got your hands on? I dabbled in CircleMud as someone else posted, but mostly Envy 2.0 or 2.2. I can't find those codebases quickly these days, but this is a link to a mud based on Envy 2.2 https://github.com/DikuMUDOmnibus/Ultra-Envy
It's from 10 years ago, a French MUD called Multimud. It's closed source because the code contains too much information about the game. It's surprisingly simple, a Perl socket-select single-thread process with no dependencies.
