Regent Symbol of Innoruuk Question

[Exuo]

I am attempting to complete the last part of the symbol quest as a DE Cleric. The problem I have is that when I try to turn in the crate of provisions to Dragoon Szorn I am KOS to him. I assume I screwed my faction grinding in Mistmoore. Is there a work around for this turn in, maybe wolf form from a druid or something? Or am I going to be forced to grind faction now to progress?

Thanks for your time and assistance.
