Nightly Guests - Atlantis Side Quest
Start Location: Gaulos Wilderness
Quest Location: Gaulos Wilderness
Objective: Obtain Shisa from a nearby cave
Nightly Guests is a Side Quest in the Atlantis Expansion Pack and begins by speaking with Jibran in Gaulos Wilderness. You can find Jibran to the northeast of the dock where you first enter the Gaulos Wildernes area; he's found in a little cubby by the shoreline.
Jibran asks you to retrieve his Shisa from the "Natural Cave" northeast of his location. You'll find the Shisa inside of a chest in the back of the cave, pick it up and return it to Jibran to complete the quest. There is another cave in the Gaulos Wilderness further north which contains an Impossible Puzzlebox inside of it. This item is used in the Mysterious Artifacts Side Quest; keep this in mind if you clear too far north and stumble across this cave instead.
