Pandora Eridian Writing Locations – Ascension Bluff
Ascension Bluff Eridian Writing 1
This particular slab of Eridian Writing is located in the far western reaches of the zone, guarded by a large bandit camp – though the writing itself lies outside of their area, you may have to fight to get to it.
You can find it on a high platform overlooking a ravine where the southern entrance to the camp is. However to reach the writing, you must take the long path up and around to the top where the printing station for the side mission – Golden Calves – takes you, and then run past it along a ledge until you reach the writing.
Promethea Eridian Writing Locations – Meridian Outskirts
There’s an Eridian Writing to be found in the Meridian Outskirts region, far off on the left side when first entering the underpass area from the fast travel jump spot.
Once you arrive in the large underpass area, head to the left to where the Side Mission Healers and Dealers leads you to a medical doctor’s room. Look at the back of the room behind the curtains to find slabs of rocks, and the writing will be among them.
