Arising from the fallen Dhakaani Empire were the Ghaal'dar. They are an alliance of tribes from the scattered remains of the old empire. Most of the lore and history of the Dhakaani Empire has been lost. This is a new alliance with their own rules and traditions forged from years of survival since the fall.
The Ghaal'dar are a simple people. They are are a warrior culture. Their focus is on building the skills and power to retake all of Khorvaire and reestablish an empire like the old Dhakaani Empire. Additionally, they show little emotion. For the the Ghaal'dar, emotions , especially fear, corrupt the warrior spirit. The emotions of fear and sorrow are seen as another enemy that can make a warrior lose focus and cause the battle to be lost.
