Quest text says: " While exploring Lake Liath, you came across another rift in time"
Should probably be: " While exploring Risen Lake, you came across another rift in time"
This is a problem if you use rift in Risen Lake and get the quest, but then leave without finishing it.
Later if you want to finish that quest, you may not know how to get there. Quest description says “Lake Liath” which is wrong era, and map indicator only points to corrupted lake. Nothing tells you that you have to go to the Risen Lake to get there.
