From Her to Eternity is the final story mini-quest in the So Mi storyline. It becomes available if you chose to kill Solomon Reed in the quest "The Killing Moon" and helped Songbird reach the Moon without any hindrance, thereby betraying the authority of the NUSA (New United States of America).

After that, in the quest "Unfinished Sympathy", Alena Xenakis will contact you and say that she was ordered to kill V. She has no intention of carrying out the orders, so have a drink with her at the bar and discuss what has happened. Immediately after that, the quest "Signal from Space" will begin.

From Her to Eternity: Walkthrough

After the conversation with Alex at "The Moth" hideout, a couple of days should pass. If you don't want to wait, you can skip time.

V will receive a message from an unknown number with strange content: "Return to the place that reminds me of home and see what you find." As you can easily guess, this message is from Songbird. You won't be able to reply to the SMS, even if you try.

A marker with coordinates will appear on the map, which you need to follow. Head to the location and scan the airtight container using "Tab." The box is located near an old sofa. After scanning the item, you will receive a Metal Token from the Tycho lunar colony and a legendary implant called Quantum Tuner.

The token hints that Songbird is alive and has safely reached the medicine. At least, one can hope for that.

Once you retrieve the items, the quest will be completed. There is no further development of the storyline.
