Rise of the Ja'zhir
Talme is home to all races from the lowly Kobolds to the uppity Eladrin. The population is very diverse though generally the less monstrous races are more well to do. However, this is a generalization not a hard rule. Likewise the slums are not all monstrous races.
Urban legend has it that a cult of Vecna operates on the east side of town. There is an old graveyard there, and it is widely rumored that cultists have been using it as a breeding ground for necromantic experiments for years.
