Update for Classic era proof.
The Symbol of Brell Quest is active and completable in game ( many drunk dwarves and gnome clerics running around) The Brell, Tunare and all other good diety Symbol quests were added to the game AFTER the evil deity quests such as Innuurok, Bertoxxulous, and Cazic.
Bertoxxulous only had the initiate symbol quest, i dont know if the disciple quest was ever added?

Quest discussion (and completion) all the way back in 2000.
Please add Diseased Bone Marrow back to brittle skeleton loot tables! :3
