Nostalrius Begins - Quality wow vanilla realm (1.12)

I have completed the first three quests in the chain, but I do not get the follow up quest called "The Azure Key", link to db:
http://db.vanillagaming.org/?quest=8236
After completing the quest "Encoded Fragments", the NPC Archmage Xylem does not provide any new quest.
It kinda is the point of the entire class quest to get the final quest, as the rewards are very..rewarding.

Could you please assist me in this matter?

Thanks,
Undercover

Bump, I'm on the same quest-chain, but once I deliver the Encoded Fragments I do not get "The Azure Key" follow-up.

I've been trying to do this quest.. (I'm lvl 53 atm) But I don't see any Rogue Trainer handing out the quest.. any idea how come?

bump
