I've been doing the Fighters Guild questline on my newest playthrough. I'm stuck on the quest "Drunk and Disorderly", where I have to put down some rowdy guild members. They told me if I fond some work for them they would get back on the straight and narrow. I was told seek out an inn keeper who had some work for the Fighters guild, but before she would trust me enough to give her jobs to the guild, I had to prove the Fighters Guild could handle itself. I was tasked with finding five Ectoplasims, which at the time seemed like an easy task. I've been looking any Alchemists that sell some or dungeons that contain ghost for quite awhile now and I havn't found anything. If anyone could tell me if any stores carry them, or the locations of any dungeons that contain ghost, I would really appreciate it.

Go to the nearest chapel, and when no one is looking, break into the undercroft (you will have to pick the lock or use a spell, so it is illegal if you are caught). You will find plenty of ghosts down there. Slay away and stock up on the goo!

I should have mentioned this before. I am Roleplaying and he is a knight. He dosn't break the law.

If you go to a vile undead dungeon you can righteously harvest sufficient ectoplasm.

http://www.uesp.net/wiki/Oblivion:Wenyandawik is one of many such ruins.

Go to Anvil and clear out the haunted ship. That should get it taken care of.

Okay, thank you very much for the help!
