Last update: 29 October 2022
On this page of the Mass Effect 3 walkthrough you will find the walkthrough for the minor side quest Hades Nexus - Prothean Sphere. This walkthrough explains, among other things, where to eavesdrop on the refugee's conversation on the Citadel and on which planet the Prothean Sphere is hidden.
Received from: Refugee [Citadel: Port - Holding Area]
Unlocked by: You will be able to start this mission after completing Priority: The Citadel #2 main quest.
This quest can be activated by overhearing a conversation between one of the refugees and the C-SEC officer. The meeting takes place in dock E28 in [Citadel: Port - Holding Area] and you'll find out that the refugee wants someone to explore Prothean ruins in the Hades Nexus in order to find a valuable artifact.
Return to the Normandy, open the galaxy map and plan a trip to the Hades Nexus (this area of the galaxy is unlocked after completing Priority: Rannoch main quest). Once you're there (Hekate system) fly to an adjacent system named Sheol. Begin scanning this system (right mouse button), but be careful as therefore you can draw the Reapers' attention. Your point of interest should be a planet named Gei Hinnom (screen above).
Hover over the planet, zoom in and start scanning its surface more precisely by holding down the right mouse button. You need to find a white dot and send a probe (left mouse button). Doing this will allow you to obtain [Prothean sphere]. Once you have the sphere return to [Citadel: Port - Holding Area] and give it to the refugee.
Notice - If you have found the sphere before starting this mission, you will be able to complete it right after it becomes unlocked, as a once found artifact cannot be lost.
Prizes for completing the mission:
- [15000 credits]
- War asset [Alliance Engineering Corps]
