SureAI

I have no imagination and need a walkthrough to depend on..
After the opening walkthrough I wandered north to Erothin, gate was locked (but I see fixed in an update), I swam around to the port
and got in that way--but now what am I supposed to do? Is there a walkthrough?
P. S. The colors look dull compared to Oblivion, especially greens. Is there an adjustment?

The wiki, http://nehrim.wikia.com/wiki/Nehrim_Wiki has a lot of guidence if that is your desire. Just remember you lose something with the game if you rely on handholding too much. Nerhim is more about exploring than just pounding through on quests.

Thank you, the wiki is indispensible to me because I have sort of tunnel vision and cannot guess what I'm supposed to do.
The most fun I had in Oblivion was climbing the cliffs around the edges of the map, just exploring. (The colors here seem
washed out.)
