Lightning Returns: FF XIII Whither Faith is a side-quest automatically triggered when you enter Luxerion for the first time.
The quest is required in order to advance through the main story, but it can also be failed if you don’t complete it by midnight on Day 1.
In case you fail the quest you will still get the chance to continue Lightning’s story but all rewards will be lost.
Because of this, the following walkthrough explains how to beat the quest as fast as possible, in order to get all corresponding rewards and also have enough time to focus on other assignments.
Description: “The body of a young woman has been found in the plaza in front of Luxerion’s North Station. It is just the latest in a string of murders in which the victim was a woman with the same color hair as Lightning. Could someone go after the savior herself? Lightning needs to question witnesses in the area and report whatever she learns to the inquisitor in charge of the investigation.”
Requirements: Complete it before 11:45 PM on Day 1
Rewards: 800 Gil, HP+80, Strength+6, Magic +6, Scholar’s Glasses
Since Whither Faith is automatically triggered, there is no way you can miss it, but you can fail to complete it; which means that you have to be fast.
The quest begins as soon as you leave the Ark and after the cutscene showing Lightning entering Luxerion.
Make sure you accept the quest, then in front of you, right in the middle of the plaza look for an Inquisitor. Talk to him for additional info, and you will be asked to find several clues for him.
After you talk to the Inquisitor, turn left and notice a red ladder. Climb it and talk to the Surveying Man on the right side of the upper platform, to get important information.
Next, without jumping down, turn around and get on the next platform to find the Fighter’s Emblem inside a sphere. Pick it up, and then talk to the officer near the dummy for more valuable information.
Jump down and head west (left) to find another officer in front of a gate. Talk to him as well (no information is provided), then return to the starting point where you have found the Inquisitor.
While in the central area look on the ground for some glowing papers and examine them for a new clue (Etro Alphabet).
Now, talk to both the Innkeeper and the Outfitter, for two additional clues. At this point, is the time to complete Where are you Holmes? side-quest by talking to Thorton near the stairs that allow you to enter the train station.
Once you beat the side-quest, you will get more valuable information and you will be inside the train station. On the other side of the same corridor you will find a Pious Cleric who can offer new info.
Talk to her, then head right inside the same station to locate a woman Resident. Make sure you talk to her as well, and then return to the Inquisitor to finish the Whither Faith side quest and the Evil Savior main quest.
