Do not get confused with doing the quest Words of Power, the high priest is in a room above this one. I spent 5 minutes running around breaking the globes thinking it spawned the high priest (similar to destroying the webs that bind the spider priest).
Just a note, he's actually inside the Spire on the left near all the blood globes.

Description
As you inspect the captured blood vial, you realize its contents are still warm. The victim must have just been bled and may still be alive. What use would the Scourge have for blood? They've never shown an interest in live prisoners in the past. Perhaps if you can locate the source of the blood, you'll be able to discover what the Scourge is planning.
