Exaltation
In order to rescue the Moshae, you’ll need to break into a Kett base located on Voeld. It was said that Angaran slaves are being brought there to work and then be killed, but that actually isn’t true. While the Kett do use slaves – something you’ll see often as you travel through Angaran planets in Mass Effect: Andromeda – the ones brought to this base are “chosen” for something else. They are to receive the gift of Exaltation, which is just as creepy as it sounds.
The reason why the Kett are so powerful and advanced is that they actually steal genetic material from other races throughout the universe. By injecting Kett DNA into their chosen, they create new versions with new abilities. They’ll take on characteristics of the original species such as the ability to survive in certain environments and combat prowess. Yet these new beings are 100% Kett. The Angaran aren’t being killed in the traditional sense where bodies are being left to rot on the ground. Their entire identity is being stripped away from them so they can serve a new leader.
The Moshae is here as well, chosen for a special Exaltation, but that’s not all. The Archon, the leader of the Kett within the Heleus Cluster, wants information from her, and it involves the vaults and the Remnant. You’ll find out a bit more about his infatuation with the technological race soon enough though.
Rescuing the Moshae is no small task; a huge battle ensues, filled with plenty of Chosen, which you now know were once Angarans. After saving the Moshae, you have a decision to make: to destroy the base or rescue the people within. Some will definitely want you to destroy it, but they’ll come to understand and accept if you don’t. Still, you can at least kill the person running the base if you want. It’s time to return to Aya, explore its vault, and learn even more about the Remnant.
