Different coloured lower clothing for argonian (and khajiit) slaves in indoril lands. Each colour represents that slave belonging to a certain Lord/State. Easy to identify.
(Note: This quest could either go in Andothren, or in Teyn in Cirifae's tradeshack - depending on if there's any felt need to add something more to do in Teyn over Andothren.)
The player might hear a line like this from latest rumours:
Nobody knows why Marobar Nerethi got kicked out of the Mages Guild. But some people believe that he put his alchemy skills to less-than-legal pursuits. Needless to say, he's not telling.
