Sir/Dame Tiltes

There has been a lot of interest about the title of "Sir" or "Dame", but unfortunately a lot of confusion and miscommunication as well.
First, this title represents a knighthood from the Sanctuary Guards. It represents the conclusion of the Marshal Kain story line on the Guardian side. As such, it is a Guardian only title. I cannot say if this or an equivalent title might be made available to Defiants at some point in the future.
Second, as this does represent the conclusion of the Marshal Kain story arc, this reward is given after all 3 pieces of his story are completed, in Scarwood, Iron Pine, and Stillmoor. There are no notoriety requirements or other achievements needed. The final quests in each of the three story arcs are: "The Last Command" (Scarwood Reach), "One Soldier to Another" (Iron Pine Peak), and "Past Is Prologue" (Stillmoor).
Third, though it is not directly related to the title of Sir or Dame, there has also been some question about the essence rewards of Necrotic Rage or Necrotic Semblance. These are also rewards related to the Marshal Kain story (and as such, are Guardian only rewards as well) and are given sometimes after the completion of the Iron Pine Peak arc of the Marshal Kain story. 
There has been a lot of confusion from players that think they have met all of the prerequisites for the Sir/Dame title, but have not. Part of this is because there is no quest players can view to confirm exactly which quests they have done. This is further exacerbated when players view their achievements and see that they have completed X/X quests for a zone. The impression is that achievement signifies that they have done ALL of the quests, but the achievement doesn't require all quests, just most.
SANCTUM* Guardian players wondering how they can be knighted as a member of the Sanctuary Guard can now speak to Sir Guysun Lawless in the Lodge of the Planes to the rear of Sanctum. Sir Guysun can direct those seeking this honor to where they may have prerequisite quests incomplete. [Kain storyline quests]
Any questions, just give me a yell and I can help you on your way. Zam Rift will also be of great help on your quest for knighthood......Pops

THanks Pops. I was actually wondering about this the other day. Although I must admit, I would rather have "Lady" as a pre-fix - as it flows better than "Dame" Lady Vaygrent The Warmonger - instead of Dame Vaygrent The Warmonger. Do you know by chance if there is a listing to all the prefix/suffix titles available in game?

@Vaygrent I think you're right that "Lady" flows better but "Lady" in the British system of peerage (which most fantasy games, books, etc. follow at least somewhat) represents a woman of noble blood and is associated with the title of "Lord". "Dame" is the equivalent of "Sir" denoting knighthood (and is a fairly modern addition).

Thank you for this information. I will check into this and work on doing the quest series on my guardian. She needs something to do while mining. :) I skipped a lot of the quests on the guardian side so I'll go back and do those.
