As usual, in this guide
I won't say anything about the story. The spoilers are simply tips if don't want to spend time exploring/looking for something/somebody or understanding how to do the things by yourself.
REQUIREMENTSAs you can see in the Codex, there are few requirements to start this quest.
First of all, you need to complete Vor's Prize and be at least Mastery Rank 1. After that, you need to complete a hunt in Cetus.
*** Spoiler - click to reveal ***To do that, you need to travel to Cetus (Earth). Once arrived, speak to Konzu inside the village (walk through the beach, enter the structure and follow the path through the mercants. At the very end, you will find an old man with a staff named Konzu). Talk to him and accept a bounty of any kind.
HOW TO START THE QUESTGo to Cetus and speak to Konzu. Choose the option "A personal favor".
SUGGESTIONSThe quest is really simple and the enemies are low-level (around 5). You can success in completing it also at the very beginning of the game (i.e. when you are at low Mastery Ranks and you have poor mods/weapons).
Just be sure to know how to use the codex scanner.
*** Spoiler - click to reveal ***You will be asked to find small shards. To find (and acquire) them, you need to go in the certain locations (the game will tell you where and when) and scan them with the codex scanner (or the Simaris version).
During the quest, you will go back and forth from the Orbiter many times. The evolution of the quest is straightforward and the quest itself will tell you what you need to do (just read what is written on the navigation system). Once in the Orbiter, to start a new step of the quest you can simply select it from the navigation (quest panel) and press A.
REWARD
BUGSThere are reports of a bug linked to this achievement. Once completed the quest, there are players who didn't have their achivement popped. All the achievements of the Plains of Eidolon can glitch. I have reports of guys having no trouble with the achievements, together with reports of random achievements glitching (one or more). It seems to affect people at random and actually it is not solved yet.
UPDATE: Digital Extremes is aware of these glitches and they will get a patch in the next future.
