if I ever have to do something like this again in my life I am going to freak
There's a quest the Gray Fox gives you, the one about retrieving the arrow of extrication, and it's supposed to go a little something like this:
- Wait for Amusei to find you in the Imperial City.
- Go to the house of Malintus Ancrus in Chorrol.
- Go to Bravil and talk to the beggars.
- Find Fathis's hidden chamber.
- Go through the secret chamber and dungeon.
- Enter Fathis' Tower.
- Steal the Arrow of Extrication.
- Go back to Ancrus's house in Chorrol and give the arrowhead to The Gray Fox.
Bravil Wizard's Grotto and the subsequent Bravil Wizard's Lair are unusual dungeons, where you will encounter Conjurers, Dremora, and possibly Daedric creatures. You will encounter a good many locked chests and doors you'll have to pick, so bring plenty of lockpicks.
As you explore you will eventually find a door that says it needs a key to be unlocked. There is in fact no key available to open this door. Instead the way through is an underwater passage. To the south of that door there is a water-filled cavern containing a very deep shaft. About ten feet down (only part of the way down) there is a tunnel on the north side of the shaft. The tunnel is located immediately below a rock "bridge" in the middle of the shaft that connects the north and south walls, and is at the same vertical level where several rays of light are clearly visible shining through the water. A slaughterfish usually guards the entrance to the tunnel. This tunnel leads around a corner then emerges out of the water on the other side of the locked door.
If you instead dive to the bottom of the deep shaft you will find an easter egg, namely a Giant Slaughterfish. This slaughterfish is leveled and can be a tough fight, especially since it is underwater. In reward, there is some nice loot. In one of the rooms with Conjurers there is a Potion of Sea (Water Breathing) which can help with getting down to the slaughterfish, although you will probably need more than just the one potion; an item with a water breathing enchantment (such as the helm Fin Gleam) is strongly recommended.
There is a passageway off the Giant Slaughterfish area that leads to a door that opens into the bottom of the Niben Bay near Bravil. The trap door has a treasure chest next to it and is located approximately straight down from the "a" in "Niben Bay" on the world map (map). This trap door can also be used as an entrance to Bravil Wizard's Grotto, if you want to bypass the first part of this dungeon.
[edit] Fathis Aren's Tower
Once you get inside the fort area, make your way to the top of the tower where you should find Fathis Aren. Rob his chest and anything else you want (but be prepared for the consequences). There are several ways you can do this. If Fathis attacks you, you may be able to lure him into falling to his death by going to the other side of the tower. For a powerful sorcerer he doesn't always look where he's going (this is also the fastest and easiest option for Mages Guild members avoiding penalty, see below). Alternatively, Fathis Aren may accept a yield if attacking and not restart fighting you. This may provide an easy way to complete the quest without killing him. You could try taking everything from his chests before yielding. Yet another possibility is that after all the minions in the tower are defeated, Fathis Aren may not move from his desk. You can speak to him and he should not attack you. If you then walk up to the chest and retrieve the arrow, Fathis should not move from his alchemy. If you need a place to hide and heal during the fight with the many minions in the tower, run all the way up the stairs and jump across the gap (you may need a high acrobatics level ie. 60+) Or, you can try taking 2 invisibility potions, use one to sneak past Fathis and loot the chest and use the other immediately after exiting the chest, if done quick enough Fathis will never even see you.
If you are in the Mages Guild: If you are caught killing Fathis or stealing from the tower you are going to be kicked out of the guild. If you are in the upper echelon of ranks in the Mages Guild, it may stop Fathis from attacking you. The easy solution is simply not to attack him first. If he attacks you, you can run away from him. In order to get out of the fort area, you need to take the arrowhead and Aren's key from his chest. You will not be penalized for taking things from this chest. Once you have the arrow and key to the front gate, you can head back down the stairs and exit the tower. Then, just run along the road until a guard or other person appears and they will attack Fathis for you, allowing you to complete the mission without being kicked out of the Mages Guild. Another method is to strike Fathis once with your sword and he will briefly disappear. At that point you can steal the key and arrow head from the chest without getting caught for stealing and without being kicked out of the Mages Guild. If you find yourself getting caught over and over again, you can make a quick escape by using Aren's Tower Key to exit the tower through the main door. He will be waiting for you, but you can lose him by making a beeline for the Nibenay Bay and swimming until you hear the music change. At this point you should be able to fast travel to a safe location. An alternative for Mages Guild members, as mentioned above, is to cause Fathis to fall to the ground below while attacking you - he will fall to his death and his corpse and chest can be looted without penalty. This is especially useful to players who wish to take the Apprentice Calcinator he possesses.
Afterwards, make your way outside the tower (through the main door) and return to the Gray Fox who will reward you with 500 gold and promote you to Master Thief. He will also tell you that you can now use Fathis Ules, who is the best fence in the guild, as your fence. However, if you have chosen to return the blade in the Sins of the Father quest, Fathis won't talk to you anymore because you didn't take the blade to him.

NOW that you've heard plenty about what is supposed to happen, I'll tell you what REALLY happened.
It couldn't have been EASIER.
So as soon as I get into the castle, some guard runs up to me out of nowhere and arrest me even when I'm not in a restricted area [tbc]
