Diku and Merc MUDs did not originally support online creation capabilities — DikuMUD was specifically designed to be a better AberMUD, which was notorious for having a hard-coded world. A number of different packages were created to add online creation capabilities, the first of these was Armageddon for DikuMUD by Dan Brumleve, Nasri Hajj, and Santiago Zorzopulos, which allowed builders to create zones, rooms, exits, objects, and mobiles interactively through a VT100 menu, or command line driven, interface. Their online creation system was added to the DikuMUD derived SillyMUD codebase, released in 1993. The Merc derived codebase "The Isles", released in 1994, also featured online creation. SMAUG, a descendant of the Diku and Merc branches, included a feature called "Online Building".
