The Sentinel's Fate contains the longest tradeskill quest line in any expansion yet. Start in The Sundered Frontier with a high elf named Felice Adae who is the Far Seas Trading Representative. She is standing at 2082, -235, 2643 not far from The Great Spire.
You must be level 80 in a tradeskill in order to get these quests.
Far Seas quests give you a Far Seas Trading Company Token with the coin reward. For a list of Far Seas faction items available, see Far Seas Faction Items. Other Odus crating factions have special recipes for crafters.
If you would like to be totally, extra-special prepared for this series, see the Shopping List, below, and go on a harvesting binge first! Also be sure to buy ALL of your fuels as there is one place with crafting stations and no Fuel Merchant or Banker.
Crafters can earn favor with four main factions in The Sentinel's Fate: the Craftkeepers of Paineel, Kerra Isle, Researchers of Quel'ule, and Hua Mein Craftsmen. The last three are each oriented towards outfitters, scholars, and craftsmen, respectively. Faction rewards include additional recipes as well as house items and other non-combat type items.
Doing the main quest line for each of the three archetype factions (Kerra, Hua Mein, and Quel'ule) should leave you at +4000 faction. There are subsequent daily missions if you wish to increase this further. If you are not the archetype that aligns with that quest faction you will only be able to complete 5/7 daily missions they offer - those of the correct archetype for that faction will have an advantage.
In addition, Alchemist Janicia in Rivervale is offering a new quest to alchemists for further dust distillation recipes.
The Hua Mein Village does not have any crafting stations, nor so they have a Banker or a Mailbox. This means that you will have to travel back to The City of Paineel to do all crafting (or to your home city, or guild hall, or whatever).

NOTE: As of the hotfix on 2/25/2010 the Quel'ule Faction Merchant, Sata, now sells fuels.
Fourteen earth days after you finish the Quel'ule series Researcher Tahar will mail you an artifact, which starts this Tradeskill Signature quest. The reward is an item with a clickable Escape (when equipped) and appearances unique to each Artisan class.
This list will supply the whole series above.
