The only way the room is going to be any more defined then a description and a bot for serving, is if you start a SITE and completely elaborate or start some huge thread explaining everything, the rules of eberron are close to the same and more open then Oerth, and almost as open as Toril. You can take my posts as ya like, just like this one, it wasn't ment offensively though. *shrugs*
If it is, making a site for it, or, crafting a huge thread on the boards then that is above and beyond since the other rooms just have each a thread for boards, ic - occ. Thats about it.
I still think its as easy as making a a description. The setting rules are the magi's calls and would probably be like Toril or the bazaar, I would have thought. So not much needed there. Half the time no one looks to deeply into the room descriptions, or goes to the -links- for further info, if any at all.
