The humanity during the time of the events in Starfield is marked by piracy, unstable politics, and exploration. After the war between the Freestar Cooperative and the United Colonies, humanity has returned to scientific discovery. During the quest "A Tree Grows In New Atlantis," Kelton Frush, a scientist studying the trees around New Atlantis, makes a disturbing discovery.
The quest "A Tree Grows In New Atlantis" can be taken on your first visit to New Atlantis, and it's a good idea to complete it as it familiarizes you with navigating through each district in New Atlantis. Additionally, you will earn experience points and a considerable amount of credits!
Travel To New Atlantis
If you are visiting New Atlantis for the first time, there's a high chance that you will pick up the activity "Speak with the scientist at the tree" after hearing a United Colonies security officer talking about the scientist.
You will find the scientist Kelton Frush and the giant tree in front of the Tram Ramp in the MAST district. Kelton will explain that he needs your help to retrieve the biosensors he has attached to trees throughout New Atlantis.
Once you agree to help Kelton, all four biosensors will be marked on your map. Since the map in Starfield can be somewhat chaotic, you can obtain information about their locations by speaking with Kelton.
We learn that Kelton has discovered that a large portion of the tree has liquefied. He explains that while a certain degree of fluidity is normal for nutrient transport in the tree, Kelton fears potential side effects that could endanger New Atlantis.
Where To Find The Four Bio-Sensors
We learn from Kelton that the four biosensors have been scattered throughout New Atlantis, which means you will have to travel across the entire city.
Where To Find Constellation Lodge Bio Sensor
The first biosensor is located outside the entrance of the Constellation Lodge, resting next to a tree. This should be the first biosensor you retrieve, as it is just a short walk up the stairs from Kelton and passes by the Double Helix statue.
Where To Find Residential Shops Bio-Sensor
You will find the next biosensor by walking past Reliant Medical from the lodge and heading towards the tree on the other side of the MAST District Lake.
Where To Find New Atlantis Corporate Park Bio-Sensor
The third biosensor is located in the New Atlantis Corporate Park in the residential district. Walk past the Mercury Towers building, and you will find the biosensor in the tree across from the Chunks grocery store.
Where To Find Commercial District Bio-Sensor
Once you arrive in the business district, go up the ramp to the level above Terrabrew Coffee and speak to Jorden Anchali to learn that he found the biosensor and sold it to Tseng at the UC Distribution Center.
How To Get Back The Bio Sensor From The UC Distribution Center
Enter the UC Distribution Center and tell Tseng that the biosensor is equipment for crucial scientific research. She will explain that she needs to make a profit to offset her losses after buying it from Jorden Anchali. To retrieve the biosensors, you can either buy them from Tseng for 100 credits or steal them from her office.
There is a United Colonies security officer guarding the office. However, you can easily take the biosensor once they leave the room.
Returning The Bio Sensors To Kelton
With all four biosensors in hand, it's time to return to Kelton and the giant tree in the MAST district.
Kelton will extract the information from the biosensors and reveal that there is indeed a problem. The tree is emitting ultra-low-frequency sound waves that are continuously increasing, without any understanding of how strong the frequency will grow. Kelton believes that this could be a disaster for the residents of New Atlantis, leading to the mission "Out On A Limb."
You will receive a modest reward of 100 experience points and a sum of credits that depends on your level for completing the quest "A Tree Grows In New Atlantis."
To start the mission "Out On A Limb," you need to wait for 24 hours before speaking to Kelton Frush again.
