Well first you need to have Frontiers. To get to Oggok u can go through the door at Urglunts wall (cyclops) or use the gatekeeper at Gerntar Mines. These 2 put you in the rathe mountans; which isnt far from oggok.
And to get to odus, u can talk to the dockmasters in Highbourne or Freeport. If u are a good class, u will go to Arcadian. if you are evil, you will go to stone of mort.
