hi guys. as velveeta on blight, i am trying to do clerash's town marshal quests, in particular the 'creepy crawly down under' quest. this means that i must attune to the port at helian's tomb, and according to the wiki, battlemaster orthondrin gives that quest. once i got to the outpost and spoke with orthondin, i was not offered the quest and am unable to enter the tomb, it still being unavailable.
can anyone help out with any info on how a biped can get the blessing/attunement to the tomb?

much thanx in advance and game on!
