Head to Lumbridge Swamp and you will see Oldak and the 4 adventurers (out of Lost City) arguing. Oldak believes they know all about the RuneScape gold fairy circles, they think he knows about Zanaris. Interrupt to point them out how to get into Zanaris and you'll be supplied 10k.

Request Oldak why he wants to know about the fairy rings, and he will say he would like to return to Yubiusk to save Zanik. Tell him about the Dramen Staff, and he will say that it is too inconvenient to visit Entrana every time he wants one, so he tells you the two of you have to visit the Dramen Tree, attempt to acquire a seed, and develop a new Dramen Tree at Dorgeshkan. Tell him you will meet him in Port Sarim.

Head to the Port Sarim pub and you will see a cutscene with Oldak asking some drunken sailors instructions to the Entrana ship. One of the sailors will begin attacking Oldak. Conquer the level 27 sailor. Talk to Oldak and you'll see a cutscene of you two sailing to Entrana. Head to the cave, past the zombies, you do not want an axe, and also to the shrub. Oldak will harvest a seed and tell you his teleorb got damaged by the demons. Instead of going there though, well, in which you property, this dialog will happen:

Where are we? This is not that city! We got them while they teleported. How could they have. . It was the sphere that they stole! They used Buy rs 3 gold it to intercept us! I knew if I got you coming off of Entrana, you would not have the ability to fight us. Now tell me, where is another filthy goblin? She is where you can not hurt her, though that's not really good...
