If you do not complete Side Quest 22: Tomboy Bandit beforehand, Kyrie (who gives you the Corneo Vault Key) won't appear at the church!
| Objective | |
|---|---|
| 1 | Speak with the News Paper Reporter in the Sector 5 Slums Station Way. |
| 2 | Complete Odd Job: Tomboy Bandit and obtain the Corneo Vault Key. |
| 3 | The first stash location can be found by opening the locked gate in Steel Mountain of the Sector 5 Slums. |
 Secter 5 Slums Steel Mountain |
|
| 4 | Once you go through the gate, you'll get the Ruby Tiara and other items. |
| 5 | Open the locked gate found in Collapsed Expressway - Caved-In Tunnel (Sector 6 Slums) |
 |
|
| 6 | Once you go through the gate, you'll get the Diamond Tiara and other items. |
| 7 | Continue through the Main Story of Chapter 14 to reach the sewers. The final locked gate will be near the end of the section. Right before fighting the Mischievous Shoat, there will be a locked gate in the Sewer System, but you won't be able to open it just yet. |
 |
|
| 8 | After fighting the Mischievous Shoat, there will be a lever to the right of the ladder that Leslie climbs that removes the water. Draw the lever. |
| 9 | Go back to the the locked gate, open it up, and continue. |
| 10 | After the locked gate, you'll come across a Sahagin Prince and two Sahagins, which you will have to battle with. After the battle ends, you will obtain the Emerald Tiara and other items. |
| 11 | After getting all three tiaras, continue through Chapter 14 until you are able to leave the sewer (after fighting Abzu). Once you are out of the sewer and receive your grappling guns, return to Evergreen Park and give them to Marle. |
| 12 | You will receive The Art of Swordplay Vol.III as a reward for completing the quest. |
If you take care of Side Quest 22: Tomboy Bandit in Chapter 14, Corneo's Secret Stash will be much smoother when you get to it.
Like in Chapter 10 before it, the sewers are accessed in Chapter 14 through the trap door in Don Corneo's Mansion. To find the third locked gate in the formal disposal area in the sewers, you'll need to continue the story by going into Don Corneo's Mansion and talking to Leslie.
Don't worry – even after completing the section of this chapter in the sewers, you'll be able to come back to the surface to complete any Side Quests you missed, so you don't have to worry about finishing everything first before continuing the story.

I assume you at least have to do "Tomboy Bandit" (causing 'Angel of the Slums' to appear where Kyrie was in the church), and "Corneo's Secret Stash" (she gives the treasure stash locations). Once these quests are completed the "Letter" is on the road from Wall Mart to begin Ch. 15, the one with "Avalanche" graffiti on the wall, find it on the ground, in the form of a card, near the enter/exit to the sewers. (Note if it still isn't there then you may need to complete all Ch.14 side quests first).

Post is a reply to "Anonymous 1" regarding "Letter from the Guardian Angel" (key item), along with an attached Elemental Materia [2]. I did receive it as well, and have put up a post detailing how I came across it.
