Lunar Threads

I recently went home for vacation again and decided to do some snooping around about L2 cheats to see if per chance anything was new. Apparently I was late on the news and I read about (call me a noob or w.e. I know a lot about Lunar, I just don't know how this got by me all this time -_-.) something called Bromide X which then trailed off into a ride through the fires of the Dark Scimitar.
However, this is not my thought/question!
I remember going through the game for fun while using a gameshark and noticed an item that came up in the inventory called the "undersea key" or something along those lines. Does anyone know what this item is or if there is anyway to test this? I have since gotten a ps3 and cannot find my ps1. I am most confident that the item was in L2:EBC. I've got the guide somewhere around the house to reference off of I just cannot find it in the guide.
Thanks

Edit: Can someone move this to the EBC area. I just noticed that I put it in the original EB. Sorry
WKL

Moved it.

Anyway, I don't recall seeing the Undersea Key anywhere in-game. It's likely one of those items that didn't make the cut but is still somewhere in the data.
...like the Dark Scimitar. KF

Just wondering if anyone else noticed it. Thanks man.

Must be an unused item, it is REAL in the sense it was programmed into the game, I just checked my item list:

...
E4AC - Rusty Dagger
C0AC - Star Dagger
9CAC - Ancient Dagger
78AC - Dagger
A0AB - Undersea Key
7CAB - Althena's Aura
58AB - Cave Key
34AB - Invitation
...

Strange considering there is nothing in the game having to do with any ocean exploring, so it would seem related to Pentagulia if anything.

(Imagining a Lunar 2 analog to the Ocean Palace in Chrono Trigger...)

Badass.

Another Lunar mystery written in code lol
Thanks again

Hmmm, I wonder if this has any ties to Eiphel having an underwater fortress at the beginning of Harmony. Maybe there were ideas tossed around for an underwater dungeon in EBC and someone remembered for Harmony?

I'd think it more likely to have been intended for the Water Ruins or even the Blue Dragon Cave.
