How to get to eastern island ??

[jake21]

I'm a bit confused or borked or maybe i just didn't read a text that poped up. I've opened the portal to deminois (sp) but before I complete that area I want to go to those other island around old broken down greenwart (like eastern island). Normally you sail and use the T command but that does not work; and when I chat with the fellow who gave me the maps and ask him to sail; he just send me to ariana which isn't very far or useful. I have a bunch of open quest (like capturing some spider) and I want to complete them before I goof and make them uncompletteable.
