I have composed a list of unique quests that I have completed during my time on oblivion. There are a few spoilers so read with caution. When more unique quests are available I will update in another article. Thanks for reading.
A Brush of Death
This quest is one of the most unique quests I have encountered in oblivion. I don't want to ruin the ruin the quest so I will just give the starting point. The quest is named ?a Brush of Death?. First visit the city of Cheydinhal and talk to a lady named Tivela Lythandas. To get to her house enter the west gate and turn right and walk till you get to a large statue look to the left her house is the first one on the right. She will tell you that her husband has disappeared and the last time she saw him he was painting in his room. When you open the door the quest will begin.
Umbra Sword
The umbra sword is one of the best swords in the game. The location of the sword is very easy to get to, but the woman holding the sword is another problem. Head southwest of Imperial city to a dungeon named Vindasel. There are not that many dangers in the dungeon, mostly rats and very simple traps to slow your progress. Woman holds the umbra and she is very tough to stop. You will have to attack her because, she will not attack you. Personal I could not take any damage off of her (level 9). The only way I could defeat her was to slide the difficulty bar sown to easy. She will drop the umbra sword and (at my level) ebony armor. There is also I rumor that she will drop glass armor at the lower levels. Getting this sword early will save you a lot of time leveling up you character.
Treasure: Umbra Sword
Ebony or Glass Armor
Lifting the Vale
I was walking around the town of Bruma and a man named Tolgan walks up and tells me Lady Carvain is looking for someone to complete a quest for her. That's how I started the quest, but you may be able to just talk to her in the castle of bruma to start the quest. The castle is on the north side of the city. In the quest?Lifting the Vale,? Lady Carvain is in search of the Dracion Madstone. She says that a group of soldiers went looking for it and never returned. She gives you a couple of clues to help you on your quest. The first clue is a diagram that leads you to Pale Pass. The second clue is a translation of an Adair dairy. If you read though the diary it first mentions Dragon claw rock. Head north on the eastern road until it dead ends and there is Dragon claw rock. The next landmark is the sentinel. Head due west and you run right into a huge statue. The sentinel is facing due north walk in the direction the statue is facing. The legend says he faces that way to say I have my eye on anyone trying to crossover the northern border. The serpents trail leads to pale pass and then to the akaviri fort. On your way to the fort you will encounter several Pale Pass trolls. These guys are big and slow. I hit them and back off (stick and move method). Once you make your way though the fort you will encounter many other Pale Pass trolls. You must kill the commander of akaviri fort. Once you have killed to the commander the door directly behind him will open to reveal the Dracion Madstone.
