Running to Riven Earth

Is it possible just to run from Eye of the North to Riven Earth?

its possible to run to all outposts.

From Eye of the North, run into the Battle Depths, and exit into Varajar Fells, then continue West through Verdant Cascades to Umbral Grotto, Vloxen Excavations, exit to Vlox's Falls, and West through Arbor Bay to Riven Earth.

yes, it may take a little while, but in eye of the north there are few places (i.e. the battledepths) that are locked. unlike other campaigns where some explorable areas or towns are locked until you finish a certain quest/mission. you have free run of EoTN. this is because the main story arc quests can be completed in any order

and as for you Covah, you can't run to central transfer chamber until you finish a certain quest...i think that is what sadchaos was getting at

You must have completed the quest Destruction's Depths to access this outpost. It is possible to join someone with Destruction's Depths, without having the Quest yourself, and enter the Central Transfer Chamber. That is from Wiki and it works

One does not simply walk in to the Central Transfer Chamber.

This always comes up xD

But anyways yeah if it isnt Factions you can basicaly run anywhere in any campaign, always a few exceptions.

well actually u can BUT you wont beable to do ATFH, i know this cause i skipped HOS by accident with a toon before and did DD,
