Prerequisite: This is immediately available once you land in Havarl.
You can activate this task by interacting with Roekarr datapads in fixed locations in the map. You have to examine all six of them, though some datapad locations will be locked until you proceed at a certain point in the main story.
In my case, I was able to activate it by finding the datapad near a Roekarr corpse, inside a rocky hollow in the northern tip of the Chasm. This is my first datapad. The next datapads are found in the locations below.
On top of a container, after the stairs leading to the platform past the bridge across the chasm. (The bridge will only be built after finding Zorai’s heirloom in the quest “A Dying Planet”)
In the Roekarr encampment of Old Pelaav, there are two datapads you can examine. The first one to the north is found inside a small shelter near the entrance and a large tank-like object.
The other one in the same immediate location is also found in a damaged, dimly-lit shelter. The datapad is found on the shelf by the door.
The fifth one is found inside Thaldyr’s home, north of the research station. This house is locked until you trigger Jaal’s loyalty mission “Jaal Ama Darav: Friend or Foe”. It’s found on the table.
The sixth datapad can be found during the sidequest “Overgrown”. After clearing out the Roekarr camp and the mutant Eiroch, search the camp for the datapad.
Location on the last map is incorrect. You have it set at the first Roekaar camp of the "Overgrown" mission on the south when it is in the second Roekaar camp you go to in the mission that is located north.
