You’ll encounter another set of stairs leading to the Creche, a location with NPCs, valuable treasures, merchants, and potential side quests.

If you aim to obtain the legendary mace, your next step is to proceed to the Inquisitor Chambers, which is also part of the Lae’zel and Remove Toadpole questlines. Remember that to obtain the item from the vendor, you must act friendly towards Githyanki first.
