Sheryl, mentioned above, was on Dune, which I think predates AmberMUSH And Lydia/Amberyl was all over the place, and created the MUSH manual (and I'm sure coded alot as well...I'm not a coder, I'm not sure).
Dune did? Huh. I recall AmberMUSH being one of the very few games in town, beyond PernMUSH, at the time I first encountered it. Of course, the old hoary place went through a large number of cycles of new groups of people suddenly discovering it. Made apping to play one of the feature characters a real bear, if you wanted any kind of respect paid to in-game history.
I could be completely wrong on that, but I thought it went Pern/Dune, then Amber, then a pause, then Masq and GarouMUSH, then Elysium/Amaranth/City of Darknes, then a sudden deluge of WoD MUSHes.
When I joined Amber, the RPG wasn't out yet.* The MUSH wasn't brand new, though...when my roommates and I ran a possesion plot with a character named ".", people though someone named Legion had returned, and that was before we joined. I was under the impression that Dune had been around pre-Amber...but I wasn't there to witness it.
And you should try to app a feature, now...it's even more convuluted.
I've looked into possibly apping Bleys, Random, Mirelle, and Fiona in the past few years, and it's convuluted as hell.
*What's freaky is that Finndo existed on the MUSH like the Finndo in the RPG, before the RPG was released. I suspect the player had inside info
