Herdir

Herdir is a supporting character in the Elder Scrolls: Oblivion video-game, appearing in the Shivering Isles and is an assistant to the player hero - despite this he is a negatively aligned character who embodies the darker qualities of madness, much like Syl, the figure whom he works under.

History
Herdir is a torturer working under Syl who becomes the assistant of the player hero after Syl makes them her Inquisitor, he meets with the hero and delights in the prospect of torturing the citizens of Dementia while uncovering the conspiracy that has consumed Syl's mind.

Throughout the quest the hero must obtain information from citizenry, often via having Herdir torture them - he will accompany the hero until the conspiracy is exposed, at which point he departs but can be seen in Syl's dungeon where he aids in the execution of the traitor the player hero helped expose.

Personality
Herdir is a very sadistic individual who enjoys the act of torture, willing to do so to both young and old of any race - he will thus torture without question at the slightest command but restrains his bloodlust, thus despite his great delight in his cruelty he justifies it as part of his service to Syl.

Abilities
Herdir's main ability is a type of magical shock that emits from his hands, much like lightning this magic causes great pain in victims - when not free-roaming he can be found in Syl's dungeon, where he has authority to lock prisoners in cells or cages and has access to an exeution machine that delivers a massive shockwave of magic that effectively electrocutes a victim to death in seconds.
