Asherons Call: Loremaster Question of the Week

While AC's major story arcs may focus on specific figures--Bael'Zharon, Martine, Gaerlan--they're still essentially about groups or races as a whole--the Shadows, Virindi, Olthoi. And even though the current story arc seems to be primarily focused on the newcomer Burun, a lot of the old guard like the Shadows and Virindi are still involved. Taking this into account, we have this week's Loremaster Question of the Week:

After the Burun/Renegade/Shadowrindi/whatever story arc comes to a close, which creatures who have never starred in their own arc would you like to see get such an arc? Which creatures would make suitable opponents for the so far undefeated Isparians? Which race has enough backstory and untapped potential to make for an entertaining story arc? And, most importantly, who would benefit best from several months of exposure with no established creatures stealing their thunder?
