Portal Servitor

Lore & Dialog
If you have not spoken to Shan Zhen in Cragstone he will not acknowledge you:

Portal Servitor tells you, "I do not know you and I do not know who sent you. I have no words to speak to you."

Once you have spoken to Shan Zhen:

Portal Servitor tells you, "I sense that the apprentices of the sword sage have sent you. This is meet by my master's wishes.  But I must ensure that you are a true friend of my master.  You must bring me three heirlooms of the House of Realaidain.  A true friend of my master would know such artifacts.  Bring me first the necklace that belonged to my master's family."
