This gnome is in the Plane of Tranquility at location (-1362, +2225, -714), outside the runed stone portal to Vegarlson (PoE A).
You say, 'Hail, Muzzrap Dirtdigger'
Muzzrap Dirtdigger says 'Hi there ______, what brings you to these parts? You wouldn't be attempting to enter the Plane of Earth I hope, it is quite dangerous in there. I have heard of mortals attempting to [seek council with the Rathe] and I would say this is a very bad idea.'
You say, 'Oh yes, I seek council with the Rathe!'
Muzzrap Dirtdigger says 'Are you crazy? Perhaps you didn't hear what I just said about how dangerous it is. Nevertheless, is is your choice and I cannot stop you. If you are going to attempt to gain access to the council and have already [obtained the necessary key] to their chamber I might be able to help. Many have told me that the force that seals the Rathe away is everchanging.
You say, 'Have I obtained the necessary key?'
Muzzrap Dirtdigger says 'Well it seems that you do not possess the Earth Infused Crystal on your key ring or your person so I have nothing further to discuss with you.'
Please post any additional information for Muzzrap and the Earth-Infused Crystal.

Tantisala Jaggedtooth drops 3 x Gem-Etched Key that opens the door to access the caves for A Mystical Arbitor of Earth (which I never found).
You need the Earth-Infused Crystal, but that page provides false information (required level of 99? PoP cap was 65) and nothing about obtaining it.

Addition:
Did the Dust Ring (a warder of dust and the fights at the center temple), then found A Mystical Arbitor of Earth was up, fought that for the appearance of A Planar Projection allowing me formal access to the Stronghold of Earth (PoE:B).
Final addition:
OH! Wait! A day after (10th) I posted this originally (9th), and now that I am proofreading this after the fact (11th) I see there is a LINK about this mysterious key!
Thank you, stealthy powers-that-be! =)
