I finally found all the cogwheel pieces! I was so happy! my first collection quest completed. I even gave up and left the Kemarr before finishing the shards. But now, I can't find that infernal Machine in the Twisting Deeps, even though I know I passed it once. I've searched everywhere I can think of. Where is it?! I've also only found one dragon weapon, the chakram. do i need to find them before going to zonra's tomb or after?

The cogwheel machine is in front of the gigantic white door of the wyrd, Go the the portal and follow each spider path from there and you'll eventually find it, and you can only find three of the Dragon Ordeals befor Zonra's tomb because the rest are in the lands of the P'gok.
