The Path of Inspiration

''The Inspired rebuilt Stormreach's Old Harbor, but are the Inspired a dream come true or a nightmare? Dare to explore and be taken beneath the Harbor, to a savage island, and into your own mind as you discover the Inspired's terrible secret.''

The Path of Inspiration story arc consists of 5 high leves quests, all take place in the Inspired Quarter. Here you fight against a Quori infiltration of Stormreach. This is initially introduced with the Update 1 and is offered to Free to Play players as an Adventure Pack.

In the Inspired Quarter town area (and Wylkes Manor), you can collect following 3 quests.
 * Dream Conspiracy (not required to advance story arc)
 * Finding the Path
 * The Shipwrecked Spy (not required to advance story arc)

Once you have Finding the Path done, head back to the Wylkes Manor and talk to the healer.
 * I Dream of Jeets

Then Jeets, the rogue will bestow you the final quest.
 * The Mindsunder

Crystal Disks and the Mindsunder optional chest
This story arc offers "end loot" in a unique way - you finish the Mindsunder quest and then inside the quest instance, you have to unlock final "optional" chest by spending Crystal Disks, one each of 4 colors. Only this "optional" chest has chance to drop unique items, so that is the only reason to run this quest chain, other than XP and favor.

End chest of other 4 quests all have guaranteed drop of Shards of specific color (sometimes you get a Disk as a lucky pull), then you can combine 3 Shards into 1 Disk at Stone of Change. Therefore, you have to grind pre-quests to get an item pull from the final quest. Disks and Shards are bound to account, thus access to account-wide bank is highly recommended.
 * Dream Conspiracy - Red
 * Finding the Path - Blue (optional chest may drop another)
 * The Shipwrecked Spy - Yellow
 * I Dream of Jeets - Green

This mechanic may somewhat penalize PuG group (you may rather don't want to spend your Disks for somebody you don't know), however, most of players seem to consider it is not that bad.
