Take Arokh to the tunnel entrance for Daemog's area and fly up about 3/4 up the mountain face. Often, the higher you go, the better for cracking through in any sort of Warp.
Daemog's is harder to crack into than Kragmor, so try to keep your patience and BE PERSISTENT.
If you get frustrated, just come back to it in a couple of minutes.
Once you get on the outside of the map using the standard techniques, work your way back down incrementally 'til you see the top of the cave. There's water in the cave, so Arokh won't accidentally land, so descend into the middle of the cave (like the centr line in a highway) then you'll be flying in that tightly enclosed space. Try not to get too far to one side or another, or Arokh may land on the shoulder/bank of the stream and you'd have to start over because he wouldn't be able to take back off.
Flap down to the end of the cave, and land on the LEFT hand side of the stream near the opening into Daemog's cavern area. walk on out and have fun.
You'll see Daemog colored blue from the shadows, hiding just inside the mouth of the ice cave.
You can have various sorts of fun, and even get a tiny bit of extra experience by killing the Grull Daemog would have.
I kind of thought that I wouldn't be able to get out, so I never saved inside Daemog's lair with Arokh in tow. I DID get out, however. Arokh was able to fit into the scavenger cave and I worked him along the entire length of it out to the exit slit. Once Arokh just came right out, once I had to do the strafe thing to get him out, much like cracking him in.
Good luck getting this done. It's one of the more unique experiences I had in the game.
I guess you've seen the Sunny Andrellians?
