Letter from -NPC- (Request)

If the Dragonborn kills Lillith Maiden-Loom in Whiterun, a courier will approach him after some hours, handing him a letter from Jervar, notifying that Jervar has no interest in the matter of killing her, but asks the Dragonborn to visit him the next time the Dragonborn is in Whiterun.

Talking to Jervar only makes him respond with his general dialogue "Need a horse? Talk to my father Skulvar." So the purpose of this letter is currently unknown and/or it appears to be a miscellaneous quest which never really made it into the game.(unconfirmed)
