Quest 1/8: Find Walter's Spirit CrystalVising the first Idol you come across. Go to sleep and talk to the old man there, Moonlight, until he mentions a friend.
Go to the next Idol and this time your friend Walter should be standing there with Moonlight. Talk to both of them to get your first fetch quest, retrieving Walter's Spirit Crystal, his pendant.
Go to the City of Desolation and kill the baddies there until you are informed that you now have the pendant. Go to the next Idol and go talk to Moonlight again. He'll tell you to talk to the Idol of Love
Quest 2/8: Find Spiritual PurityOnce you find an Idol of Love, talk to her, she'll tell you to find 5 pieces of Spritual Purity, all of which are in the Hall of Arrogance, keep an eye out as they appear randomly (they look like glowing gold orbs).
It may take multiple run throughs to find all 5 in the Library & Vestibule areas. Once you have all 5, go talk to the Idol of Love.
Quest 3/8: Find Heart of a HeroGo to sleep and talk to Moonlight first to get the key to where Curian is locked up, then head to the last area of the City of Desolation and go to the door that is normally locked. Defeat Curian and find the Idol of Love.
Once you have the Will of Purity, snooze and talk to the old man. Encablossa butts in for a second. Wake up, continue to the next area then sleep again.
Quest 4/8: Find the Glass of SerenityTalk to Moonlight who'll give you a riddle. Figure it out or don't, just head to the Hall of Arrogance where you'll have to fight through both levels of the Vestibule & Library as well as the Twilight Corridor and then warp back to the Antechamber.
Head toward the Atrium again but this time at the warp, chose no and there'll be a staircase in the next room to descend and find the Glass of Serenity. Remember, you MUST fight through all three areas first or the staircase won't be there.
Quest 5/8: Find the Water of Embracing TimeSleep and talk.He'll tell you about the Water of Embracing Time. Head to the Forest of Embracing. It's in the first area, at the part with the massive waterfall. It'll look like a glowing golden orb. Once you have it, find an Idol and sleep.
Quest 6/8: Find the Books of TruthThis time you find Encablossa again and he'll tell you to find 3 Books of Truth. Head to the Hall of Arrogance to find the books.
Basta37 has provided this link to this having issues with the books -
http://www.xboxachievements.com/forum/showthread.php?p=61567...Like the Spiritual Purity stuff, these books show up completely randomly although, always the first floor and occasionally in the Twilight Corridor. If you can get two in one run through, count yourself lucky. Once you have all three, sleep and talk.
You'll need to go to a different Idol and sleep again to talk to Moonlight, who'll tell you to throw the Glass of Serenity away. You have to do this in the Cave of Rage so head there.
Quest 7/8: Dispose of the Glass of SerenityHead to the bridge in the Cave of Rage which should be right before the stairwell down to the Balrog's area. You know you're in the right area if you see one of those familiar glowing orbs again. Walk into it and you've thrown the Glass of Serenity away. A notice should pop up that you've done it.
Sleep at the next Idol to talk to Encablossa and get the key to the dimension gap which is in in the final area of the Road of Chaos on the second level, right before the battle with Encablossa. Walk into the orb up there and you are on your way to a brand new boss battle, namely Keither.
Quest 8/8: Defeat Keither + EncablossaThe thing to remember here is that Keither draws his power from the clock so when he becomes invincible, tear the clock up first and then lay into him. It's a relatively easy boss battle. Once he's dead, sleep for a cutscene or just proceed straight to the Encablossa battle.
