Drider which focuses on underdark and mostly conquering underdark as her realm as she envies the drows who did not get mutated? Or perhaps envy Lolth herself and seek overcome her entirely in her supreme arrogance? Envy the surface elves? Either of those works :). She would have 6 levels to work with as well (6 CL either as cleric or sorcerer, although I think considering if her goals is to overcome Lolth, she should have sorcerer/wizard levels instead). Thus she can qualify for caster/divine PrC's (perhaps even as warlock, although that could be better served by cohort). So overall drows and underdark themes minions/servants.<br/><br/>Gluttony; how about very blood thirsty vampire? A vampire countess who's gluttony shows in sheer amount of blood she wants to drink and feast upon (a bloodlust which existed even while she was a mortal; a total rip off from Elizabeth Báthory (http://en.wikipedia.org/wiki/Elizabeth_B%C3%A1thory) story where in end she transformed into vampire upon her death/execution). To make things different she would be shadowcaster (http://dndtools.eu/classes/shadowcaster/) and thus her minions and followers would be practitioners of shadow magic (from Tome of Magic). As vampire template adds only +2 to CR so she could be 11th level.<br/><br/>Or perhaps even full levels in Master Vampire (http://dndtools.eu/classes/master-vampire/) so she is 10th level shadowcaster in CL wise but got more useful class features than useless Sustaining Shadows (although umbral sight is pretty awesome) from 10th level.
