When you first enter the Antechamber, you will be attacked by Bane. Kill them head right and examine the rune there Lore (40) check. Head back outside to speak with Zdenya.
Open your inventory and examine the rubbing to advance the Stirring Visions quest. Then loot the containers and head left. Look for the (hidden) brick on the wall containing many health potions and some camping supplies. Just past that are some more containers to loot and you'll start to hear creepy noises.
