Fastest way from tanvu is to take the teleporter at the docks to Khal. Once there turn and go over the wall down to the docks again to the left side teleporter at the Khal docks and let him port you to Ahgram.
There you ride around the main city (just leave the docks to the right and ride around and along ahgram - if you follow the pathway you will automatically ride towards the mining company and pass Donovans Roost on your right on the way. (It's a little encampement with a few people right hand side up a bit on the hill). If you see scorpions, whirlwinds, jackals and giant spiders you are on the right track
