Celtic Heroes

I'm on the level 133 as a druid. My questline took me to Dunskeig Sewers and other than the armor (Frozen or Frost) in the OW there doesn't seems to be any other quests to do or anywhere else to go.
By the way, thanks to my clan, I got the quest for the bridge finished, but I am still under leveled.
Any help? Thanks.

Arbiter Kester in OW and the dude next to let in Carrie has the Razor repeatable quest.

or the skir quest in sewers

I think you need to be level 135 in order to unlock the next quest
