Ana has an idea that's just unconventional enough to work. She recounts how the Iron Lord known as Felwinter was actually an AI developed by Rasputin and installed into an Exo frame.
Her plan is to download latent data from the shards of Felwinter's Ghost and reintegrate them as if he were a submind himself.
"Missing pieces of Rasputin's code, linguistic data, pieces of Felwinter's personality engram… We can use it all!" she exclaims.
Saladin has granted you access to the Ghost's shards at the Iron Temple. This could prove to be the breakthrough you need.
