After examining the quest starter, you must find four Druzaic Shrines in the Shattered Lands.
Note:Each shrine can spawn in two different zones, about once an hour. they can be up in both zones or not at all(Also, in one zone and not in the other). However, keep in mind that there is a delay between the shrine appearing in each of its locations. The delay seems to be anywhere from a few moments to up to 45 minutes in some cases.
