The Ziggurat Gate Keeper is an ancient gate keeper responsible for 8 Necropolis and 6 Catacombs. He was once human, but his soul was sealed by an ancient magic, and he must endure hardships watching the Underground Temple. He asks you to find the Ancient Scroll he needs to dissolve the Seal. Can his hope be realized? Why is the Trader of Mammon collecting empty scrolls...?
1) This quest starts wit the Gatekeeper Ziggurat, which can be found in any catacomb or necropolis. Speak to it to start the quest. It tells you to hunt certain mobs to obtain scrolls of ancient magic which you can trade for blank scrolls, which you can use to buy things at the Merchant of Mammon. It says to kill mobs with names such as Watchman, Watcher, Sentinel, Monk, Overlord, Priest, Archon, Inquistor, Guardian, Elder, Royal Guard, Preacher.
It tells you not to touch Nephilims, Lilims, Giants, and Lithes but it's an idle threat, it's not going to do anything to you about it.
2) Hunting these mobs will give you quest items of Scroll of Ancient Magic, when you have any amount of them go back to the Ziggurat and trade them 1 to 1.
