This NPC Responds to me when I have Platinum Efreeti Armor in my bags. At this point I have already finished task 5 of Noble Sivrn's solo tasks, so I do not know if this has anything to do with it. Here's what he says concerning the pieces and my hailing:
[Fri Mar 16 00:27:03 2007] You say, 'Hail, Noble Phren'
[Fri Mar 16 00:27:03 2007] Noble Phren looks at you curiously, 'Is that Platinum Efreeti [armor] that you are carrying there with you?'
You say, 'what armor?'
[Fri Mar 16 00:27:16 2007] Noble Phren says 'It may interest you to learn that Efreeti are not all equal in intellect. That armor you carry is a type of identifier that allows the more simple of my kind to identify one another... Although the armor you carry seems to bear odd markings, would you mind if I examined it more closely?'
Breastplate
[Fri Mar 16 00:27:34 2007] Noble Phren touches the strange symbols and reads, 'Azia looks to the west, and sees Izah in the far distance.'
Legs
[Fri Mar 16 00:27:47 2007] Noble Phren says 'The inscription on this piece reads, 'From his corner, Kala opposes Geza in his corner.''
Arms
[Fri Mar 16 00:27:56 2007] Noble Phren tilts the armor to view it in better light, 'Caza is surrounded by seven mutual allies, and one mutual enemy directly North, while Ozah is surrounded by enemies on all sides and corners.'
Hands
[Fri Mar 16 00:28:05 2007] Noble Phren says 'Odd, there is an inscription on this piece... 'Lena avoids the board perimeter while Jaka does not, and the Northeast remains vacant.''
Bracer
[Fri Mar 16 00:28:16 2007] Noble Phren reads quietly as he studies the armor, 'Meda stands neither in the East or the West, Heda stands neither in the North or the South.'
Feet
[Fri Mar 16 00:28:26 2007] Noble Phren says 'It seems as though someone has scribed these words into the armor itself, 'As Ena faces from North to West to South, he sees Lena, Neza, and Beza.''
Helm
[Fri Mar 16 00:28:47 2007] Noble Phren says 'This armor mentions our missing brother, Paza, how strange as he is believed to be dead... 'Geza stands directly East of Jaka, while Fana stands watch, awaiting the return of Paza.''
Mask
[Fri Mar 16 00:29:50 2007] Noble Phren studies the mask for a moment, "The wisdom of Ateleka guides those who seek knowledge.
