Elonian noob here :)

Hi guys, when I hit lvl 8 with my Dervish decided for my secondary: I spoke to the paragon trainers I could find in the Churrhir Fields area and done the choosing.
Later I revisited the area with a guildie and discovered that is possible to actually visit even the area where the first mission took place... and this location is full of npc's too!!
Did I miss some valuable skills? are also the npc's in the area with the catapults and sunken ships able to teach you skills for Dervish and Paragon?

I know there are paragon trainers in those areas as I have just started a paragon myself. Not that obvious, I grant you that...I certainly never found that out myself during the trial..
