Karrabukk at the end of the island questline on Deathweave Isle. He's supposed to set up the Bilgewater falls Mini dungeon. Instead, all I get is a threat from him. I can't progress any further. Character name is Xusha.
I suspect you have not started "Shattered Seas: Chasing Greymast", yet. You can get this Signature quest from either Harbinger Gloska (evil aligned characters) or Murrar Shar (good aligned characters). ~ Kaitheel
