Where to find the Watcher’s Nest Computer Code?

To get the Watcher’s Nest Computer Code, you will normally have to unlock the Senedra Forest missables. To do this, you need to do the following:

  • Take the "Lymbic Rod - Grief, Z" iconLymbic Rod - Grief, Z from the tomb in the Watcher’s Nest.
  • Head into Act 2 and unlock the second part of the Vyssa Hills area via the Ecstasy quest in the Pathom Abbey / Lethe - National Library
    • From here, you will get the mine key, which will allow you to open the doors to the mine shafts you’ve found. Go to the one on the pathway towards the Vigil after climbing and progressing through the obelisk and gravestone pathway.
    • Go down that ladder, and then one the door to the red room to get the "Lymbic Rod - Grief, V" iconLymbic Rod - Grief, V, and the note from the body.

Take a look at that note, you will find the Watcher’s Nest Computer Code is: 241244. You can infer it based on the hours in the day, the months in a year, and the four corner and four seasons commentary on the note. Now return back to the Watcher’s Nest and input that code.

You will now reveal a few documents relating to the Watcher’s Nest. One details an attack on the Vigil member by OMSIF. The other mentions the Senedra Forest Timeloop, located inside the hilltop fort room. You need the Lymbic keys we mentioned above to open it and investigate it.

Reading both documents will now end the Eternity Mystery, marking another one you have completed on your journey. Also, with the notes and rods you have, you can now open the Senedra Forest Hilltop ruin, and get access to that Timeloop. There’s other rewards, and another completed mystery awaiting you for it.
