Warning: This miniquest will take people into dangerous parts of the Wilderness. Beware of player killers and that you can not teleport after level 20 wilderness
All of the Mysterious ghosts appear at all three of their possible locations but only one of the three will give you their piece of the set.
He will tell you where to find Rennard. The location of all the subsequent ghosts is randomised but is hinted by the previous ghost. Rennard will be in one of the following places. If you go to the wrong location, a ghost will be there but you will have a meaningless conversation with it.
Graveyard of Shadows (Wilderness, Carrallangar); if you get this location, the zombies and ghosts will be aggressive and will interrupt your conversation. It may take a while to get your conversation finished.
End of the Lava Maze (Wilderness) you will need a knife or other sharp object to cut through web.
Special note: If you go to a different location than the one Rennard tells you, you will NOT get the boots and instead you will have a normal conversation and nothing to do with the story.
Head to this location and talk to Kharrim. He will give you some Ghostly boots and ask you to find Lennissa.
Lennissa.
From him you learn that Zamorak was a mortal Mahjarrat, and that what he did with the Staff of Armadyl caused the "other gods" to banish him, although Saradomin must have had foreknowledge of the mysterious event.
The earth warriors can be rather annoying, seeing as there aren't many places to trap them, but with some luck, you CAN trap the Earth warriors behind the ghost, with you on the other side, you must talk to Viggora as soon as this happens and click through the first dialogue window to make this effect permanent for the whole chat.
Listen to what he has to say and then he will give you the final robe piece, the Ghostly cloak.
Note: If Dhalak has given you a clue involving a castle in the "dark lands," the correct location is the Canifis Slayer Tower.
Upon completion, you can talk to Historian Minas on the 1st floor of the Varrock Museum and receive 10 kudos and a lamp which gives 10,000 experience in any skill above 50.

Trivia
File:Somebody set us up the bomb!.pngA player references Zero WingIf you speak to any of the ghosts without a Ghostspeak amulet, your character may say "all your base are belong to us", as well as some other quotes. These are references to famous translation errors in the game Zero Wing.
According to Dhalak, the Canifis Slayer Tower was once Viggora's own castle. Viggora himself also confirms that he (among Zamorak's other major followers) were given a large amount of land as a reward, and the Slayer Tower is most likely evidence of that (as Castle Drakan belongs to Lord Drakan).
If you lose any part of your ghostly robe set, you will have to go back to the ghost that you got it from.
It is possible to have more than one set of ghostly robes by dropping the part that is wanted and talking to the ghost again. (NOTE: You must not have any of the robes that you want in your bank).
When speaking to Rennard, your player says "I ain't scared of no ghost," a possible spin-off of "I ain't afraid of no ghost" from the Ghostbusters theme song.
If you have 99 magic, when talking to Dhalak he will ask you "Be you some mighty sorcerer to bind me or so?" and you will reply "Well, I don't mean to brag, but I guess I am with my 99 magic..."
If you wear the Ghostly Robes with Ava's Attractor/Accumulator and you look straight through your chest, you will not see it, despite the fact that you can see other things through the robes. The same goes for wearing a necklace or amulet and looking through your back. (This bug has now been patched.)
If you equip a ring of visibility that is in your inventory while you have one already equipped, you will not be able to see the ghosts. You have to un-equip the ring that you are currently wearing, and re-equip it in order to see the ghosts again.
If you wear your Ring of visibility and Ghostspeak amulet and speak to the Scout just south of Shantay's Pass, he will say, "You can see into the shadow world, but you are not of it. I do not trust you." or "A mere mortal can see into the Shadow Realm? The General will want to know of this." or "Spy! I shall kill you!" or "Begone, you filthy human! I spare no words for you." The chat box will also say, "They object to your opaque clothes." If you wear the ghostly robe set and talk to him, he will say, "A skinbag in the shadow realm? Khazard will want to know of this." This is referring to the Shadow Sword miniquest.
There was a glitch that if you lost your Ghostly Robes, you were not able to retrieve your Ghostly Boots. This glitch has been fixed.
