well, the dragon trainers have taught you all they can. make yourself at home, exploration-wise - check out the other types of baddies, do some more crafting, whatever you desire. when you are ready, you can head to the new trismus portal and the wider world.
you wil become very familiar with portals or travel gates. some guild and plot islands and settlements can only be reached by portal. you must be attuned to some ports to use them. you do that by speaking to the gatekeeper for that particular gate. some gatekeepers require you to do quests before they will grant access (trandalar ports, for example).
of course, all this is explained, at least briefly, when you first approach the port to new trismus. there is only one real road on the island, so just head east on it and when you run out of land, you are there!
when you first approach the portal, the destination menu will pop up along with the first page of the explanation dialog. there are five pages in total, so as to provide some basic info about the game tool you will be using the most.
so, now you are on new trismus!!! i will introduce you next time, and after that, i will bring out mourningwood to show around to the dragon trainers, craft and adventure! hope you are looking forward to it like i am, it will be a great refresher for me - some places i may even explore for the first time in years! se ya soon!
