Sir Trodonis wants you to search for a dwarf in the "basement of Castle Mistmoore," which is actually Mistmoore Catacombs. He's in the room with the non-aggro thralls reached by the southern ascent The Artery ( -86, -31, 83 ) /waypoint -86, -31, 83.
Note: If you have Dust of Recollection, blood of the Thrall, or Evil Eye Bile in your bags or bank (received previously when someone in your group was on these steps of the quest) destroy them before continuing. You will not be able to loot another since it is LORE and they will not automatically update the quests.
Go into the room right next to the dwarf and click the scroll on the table ( -67, -31, 95 ) /waypoint -67, -31, 95.
Obtain a Dust of Recollection by killing any one of the following:
Head Maid Z'yra ( -97, -27, -66 ) /waypoint -97, -27, -66. If you choose to acquire the dust from Z'yra, clear the room since you'll need the room clear anyway for the next step.
Obtain four bottles of blood of the Thrall. Harvest these in the maid room as Libation Winery ( -78, -27, -69 ) /waypoint -78, -27, -69. The box remains.
Obtain four bottles of Evil Eye Bile. Get these as body drops off mobs in The Blood Forge ( -127, -28, -25 ) /waypoint -127, -28, -25. Enough should drop to update everyone in the group so plan your looting.
Enter Castle Mistmoore (yay!). "Find a use for the Blade of Zane, the miniature sword replica."
Find a chest, then pick up a book at ( -90, 0, -20 ) /waypoint -90, 0, -20. This is inside a small room near the epicx2 named in the basement (reachable via main entrance). Use invis to avoid aggro from trash mobs near the epic named. Use right mouse click and use the sword on the book.
Gather pages for the Eternal Bloom book
Page #2: ( -135, 0, -48 ) /waypoint -135, 0, -48 (Room between ballroom and Vikmont)
Click the skull on the stick in The Secret Stash, a small room ( -87, 0, 8 ) /waypoint -87, 0, 8 just before Vikomt D'Raethe (not where coffin and book were) which can be opened by clicking vase at ( -60, 0, 3 ) /waypoint -59.8, 0, 2.8.
Get 10 pieces of drop of Mistmoore rust for each member of group (common chest drop from any living statue including those near small room) NOTE: as of 3/20/10 the statues must con to drop the chests (Grey mobs will not drop).
Click skull again and use rust on it.
Click portrait of Zanne on wall ( -189, -9, -12 ) /waypoint -189, -9, -12 near entrance to Mistmoore Catacombs where Bloodsteel or his placeholder usually stands.
Kill 9 named monsters or their placeholders in the castle to get updates (the following is ordered to match the quest journal):
"Find the heart of diamond on a sentry of pools or the stones of leering" by killing the Guardian of the Bath or any leering gargoyle e.g. in front of towers ( -177, 0, 0 ) /waypoint -177, 0, 0 (Basement, in the bathhouse just off Vikomt's chamber.

Locate Mayong's bust in the basement ( -102, -5, 59 ) /waypoint -102, -5, 59.
This is just down the hall to the South of the Vikomt's chamber. This is the room adjacent to Fountain Room and before going west toward a Honored Lord. The bust just at the right when entering from the Vikomt room. It is relatively high up, so KEEP AN EYE OUT FOR IT!
Right click on it and place the eyes and the stones to receive the Blade of Mistmyr.
Return to the chest and use the blade to open it ( -90, 0, -20 ) /waypoint -90, 0, -20 to collect Soulfire's blade.
