Heres an Example of one.
A Dark Elf Revolutionary named Amaraz Indobar, has been hunting officials of the Argonian Empire/Nation? He hunts any officials, dignitaries, ambassadors, etc etc...the officials could be Human, Mer, Khajiit, Argonian, or even his own people the Dunmer. He still kills them in an effort to weaken Argonian power in Morrowind, and prevent influence or friendship from developing between them and Skyrim. He is a Nightblade type character. A true Dunmer stereotype. Combining sorcery, stealth, and his bloodstained blades to accomplish his goals.
He gives the Perk Assassins Etiquette-Giving advice on how to be an Assassin, Amaraz gives a bonus of 15 to your Sneak, Illusion, and One handed weapons skills.
His story begins with you witnessing the death of a Female Argonian and a Male High Elf. Both who were fleeing from a burning carriage. You stumble upon the scene and watch him burn one and then run the other through effortlessly. Impressed in spite of your reservations you are curious and talk to him. Eventually deciding to kill him, leave him alone, or enlist his help.
If you tell him to go away you can find him later. If you enlist his help he becomes your companion and you eventually learn that his sister betrayed his entire family to their deaths during the Argonian invasion. He knows she is now a ruthless official and assassin employed by the Argonian Leaders. He figures that if he kills enough officials then he can weaken the government he hates and hopefully draw out his traitorous sister. When he hears of her coming to find him through his connections, a plan is implemented in which he lays an ambush for his dear sis.
You attack a small troop of about 10 dark elves and his sister. These are Ebony Knights. Specially equipped Dunmer with complete martial training. Ebony armor and Arms. (Quest for him doesn't activate till your char gets to a certain level) Amaraz ambushes them in a scripted event that kills 5 of the knights and then rushes them while several are knocked on the ground...explosive trap spell? You fight and kill all the knights and then once his sisters health, who's name is Iveri Indobar, is brought to about one half she knocks out until the end of combat. Once combat is over Almaz grabs his sister and is screaming at her about why she betrayed them and decides to kill her. At this point you can convince him to mutilate her hands a bit, effectively ruining her career as an assassin. Or let him kill her. That gets you a choice of two bonus perks.
If you let him kill her He gains the Sated Vengeance Perk-Due to having gained closure to his families ordeal, Amaraz realizes that he must be stronger to prevent anything like this from happening ever again. He gets a 30% bonus to Damage and a 30% bonus to damage resistance.
If you convince him to spare her you gain the Blood Wisdom Perk-This enables Amaraz to let down his guard and teach you secrets of his family who once were renowned spellswords. His advice allows you to gain a 30% faster casting time and a 20% boost to your magicka while having him as a companion.
