Introduction
Like other collectibles, Mem Fragments can be scanned for information. These fragments explain the story of characters in Fortuna. This guide shows where to find them.
If you want to find them without help, look in places people would normally go. They are often near important places or hidden in caves. Some are in less common areas, and one is in a hard-to-reach spot. All locations are reachable, but if you need help, this guide will show you where to go.
Overview
These fragments look like Debt-bonds of various colors hidden all across Orb Vallis. Unlike Kurias, they don’t make a sound nor do they show up on the minimap with loot detection mods like Cephalon Fragments. Your only cue is your scanner that highlights them in orange (or green if you’ve already scanned them).
There are 35 fragments total, 5 per each major Fortuna character:
- Eudico
- Legs
- Little Duck
- Rude Zuud
- Smokefinger
- The Business
- Ticker

Helios would be of great help in finding the fragments. While it’s technically possible to get everything on foot, an Archwing is highly recommended. If getting a fragment on a base is bothersome due to enemies, you can capture the base to disable spawns.
Although fragments seem to have a set number, they will be unlocking from 1 to 5 regardless of what was shown when you scanned the fragment, as apparently intended by DE. The fragments in this guide are sorted according to their in-game number seen on scans.
It seems that there are no special rewards for getting all the fragments like for Kurias or Thousand-year fish.
This helped a lot, thank you very much! U are amazing! <3
An image of the entire map, with numbers/waypoints of where these fragments can be located would be helpful, as I’ve yet to memorize which caves are where
some of these pictures dont help at all and im so confused. Especially around the business’s fragment 3/5 like u put a generic location completely seperate from where it actually is i spent 20 minutes looking for the exact location because the map is transparent and idk where the fuck i am holy shit
Very useful info: You can tell which fragments you specifically missed in the Codex by looking at the bottom bar on each fragment. If its filled you already got that specific number, ifs not filled, you didn’t collect it yet.
