A bit frustrated trying to find Skyshard (4), On the lip of the Skybridge?
There are two elevators up to the Skybridge. The easiest and closest is one in the south part of the Rector District (Western Area) of the Brass Fortress. Please be advised that the path to the elevator is guarded by Factotums.
I ran into a researcher in the city wing of Shada’s Tear who told me that the rest of her research team drank the cursed waters of Shada’s Tear and went mad. She asked me to save her friend, Nahlia, who was catured by the mad researchers.
Tip: A group of three or four is recommended for this quest line. However, can be done with less but will take longer.
