Steelfang Bloodline

The powerful strain of Vampirism that comprises the Steelfang strain is actually originated from the blood of the Steelfang family/bloodline. Many of those who have the Steelfang Strain are born with it from birth and descended from the Battlemage Sorin Steelfang, who was the first Steelfang Vampire.

Details
All Steelfang family members are gifted with the "awakened" strain from birth and are descended directly from Meridia, which also explains their angelic wings when they manifest their true forms. All members of the Steelfang family descended from Sorin possess light blue irises, slit pupils and white hair, which serves to differentiate them from all other bloodlines, since nobody else (no other Bretons, to be precise, despite the fact the line is descended from Altmer, Breton, Akaviri and Nordic blood, since the Steelfangs are considered Breton) possesses those traits. Furthermore, no human possesses slit irises. Steelfang Family members have eyes that glow blue in the dark.

These individuals can grant an "awakened" strain to a people that they love deeply without the transfer of blood. This grants the one that is turned the ability to use powers limited to the Steelfang line, such as the fear vision, access to Euphoria and the ability to summon its denizens, an innate affinity for learning magic and powers, in addition to what they already have. Individuals also receive immense boosts to all the innate powers of a normal Steelfang Vampire, as the infection reprograms their genetic structure. As they are part daedra, all members of the Steelfang family can enter Oblivion easily, while their mortal halves prevent then from getting banished by spells. All of the Steelfang family are capable of planeswalking, therefore. A few members can even journey into the void and beyond the Aurbis, such as Siris, Horus, Raydin and Lamia.

Granting the "awakened strain" was how Alyssa Steelfang, Tavion Wolfbrood and Lucina Sea-Born were turned. Virlomi was first turned by her unborn children Isis and Horus, then she was turned into a main line member via the special turning process by Raydin. This granting of the "awakened strain" is similar to an act of consummating a marriage and is irreversible, binding the destinies of the two partners together via an emotional bond, which is why it can only be passed between lovers.

All members of the Steelfang clan seem to possess a personal sword, of extreme power, which is generally reflective of their powers. These swords tend to possess strange traits and are generally forged by pure will on the part of the Steelfang themselves (with the exception of "Fatality's Endeavour", which was precipitated from Raydin's immense powers by Molag Bal, or "Reaper of Souls", which was a cosmic weapon that forged itself in the void). These weapons are all unbreakable and when a Steelfang family member needs them, since it is not stored on the body, it is summoned, not drawn from a scabbard. Many of the Steelfang family members are reluctant to use these weapons as them result in mass collateral damage if not carefully employed.

Many Steelfang clan members also possess an alternate, weaker weapon that they can use other than their personal sword. These weapons are still very deadly pieces of equipment that can cause considerable damage if used irresponsibly. Unlike their personal sword, these weapons can take on any form, and they are in fact rarely swords.

Powers and Abilities
All Steelfang family members possess the extreme basal abilities of a normal Steelfang vampire, enhanced beyond the baseline. They possess far superhuman strength, speed and reflexes. While a normal Steelfang vampire possesses very high durability, a Steelfang family member possesses "Divine Skin", which completely nullifies all magic performed with non cosmic power by absorption of it as magicka. This Divine skin also completely negates all physical attacks not performed with a high grade cosmic/divine grade weapon, making them invincible to almost all normal attacks. Even against divine and cosmic magic or weaponry, the Divine Skin still provides very high level of protection.

The Vitakinetic power of a Steelfang family member is far higher than that of a normal Steelfang Vampire, granting them infinite life force. This allows them to regenerate from even a single cell if necessary, and can even perform a time reversal based healing to recreate the body from nothing via violation of causality. Due to their infinite life force, Steelfang family members also can fire off extremely powerful blasts of life energy that cause extreme devastation.

Steelfang family members have a fear inducing vision that can drive targets insane or even kill them through paralysis of the whole body. This ability only activates upon puberty and is exclusive to Sorin's descendants. Other vampires who carry the Steelfang blood do not manifest this ability. Steelfang vampires cannot use this ability on other Steelfang vampires, or they risk blindness. The more powerful the fear vision, the more likely a Steelfang vampire will injure themself when locking eyes with another Steelfang Vampire and exerting the ability. Female members of the Steelfang family seem to have a much stronger fear vision by default. For example, Annalyse has a more powerful fear vision than her father even without training, being able to paralyse and kill in seconds, while Raydin cannot kill with his fear vision. This ability is thought to be descended from Alyssa and Sorin lacked it or never used it. The ability requires direct eye contact, but it will work on blind people.

The fear vision of a Steelfang vampire descended from Sorin, if used to stare into the eyes of someone the Steelfang vampire is interested in or loves, can create endless beauty and a sense of happiness in the target, rather than unlimited fear. It amplifies positive feelings instead of negative ones. The sensations the vision amplifies applies both to emotions and physical sensations.
