Cazic Thule is ALL about fear, pain, and terror. Sound like fun to you? Then you are just the sort of vile evil that Cazic Thule is looking for to join his ranks! You will have to earn his respect first of course, but once that is done, you will be rewarded.

Once you have completed your first deity quest for Cazic Thule, you will be rewarded with favor and an altar for your home. You will gain more favor by completing the other quests for your deity or by giving offerings to your altar, and may use this favor to purchase blessings and miracles that can be helpful to you during combat.
