help with sixth house mod

[Coot]

I'm enjoying the heck out of Endrek's Sixth House mod. I'm stuck now, though, because for the life of me, I can't find the "... three extraordinary powerful Buoyant Armigers" who are "...headed up the western slopes of the mountain toward Endusal".
After reaching Endusal I've searched everywhere (well, not really everywhere, else I would've found them) on the ground and in the air, but they don't seem to be there.
Can someone send me in the right direction without spoilers? I'm getting tired of flying through ash storms.
