This is something I posted to Alla, but cross-posting here for visibility. The more I think about this the more I think it's correct.
I have a strong theory on how these two armor sets are obtained:
First off, it involvs Limbus. We did Limbus the other day and after clearing it, a regular Rare/Ex item dropped called "Ivory Chip". The description said something about indentations, can't remember exactly. Anyway, near the entrance to Limbus, there is a message when you click something that says something like "There are multiple six-sided indentations here."
2+2=4 right?
What I think is that you gather some combination of these chips, trade it to that target, and boom, something happens.
But what happens?
Well, consider this:
There are 2 Limbus areas, Temenos and Apollyon
There are hints in the DAT files of battles against 2 boss type monsters, Ultima and Omega.
There are 2 sets of mysterious armor, Nashira and Homam
There are 5 pieces of Homam armor.
There are 5 pieces of Nashira armor.
There are 5 items in the DAT files related to "tissue from Ultima".
There are 5 items in the DAT files related to "tissue from Omega"
There is an NPC in the middle of Al'Taieu named "Esha'ntarl" with no known way of getting to him.
There is a zone in the DAT files in the Lumoria region called "The Last Stand" (fitting name if that's the where the real boss of Limbus is, eh?)
There is text in the DAT files for "The Last Stand" that has references of "fighting", and text for menus like "Do you want to give up?"
So put 2 and 2 together, and I think you see what I'm getting at.
