Genius of the Blade (+5C, +50 to melee rolls, more likely to gain swordsmanship traits)- Jacob Oakheart has a natural talent for the blade that no amount of training or experience can mimic, a talent that allowed him to kill an Ammut Crocodile with a dagger at the age of five.
Heir of Oakheart (+1M, +4I, +2P, +4C, far less likely to die)- Jacob Oakheart was raised by Arbitrator Jane Oakheart, the greatest swordsman on Avernus and the Founder of the Oakheart School of Swordsmanship. As such he was subjected to a level of training that would have broken a lesser man for a major portion of his life.

Master of the Oakheart Style- (+2I, +2P, +5C, +50 to all melee rolls)- Jacob Oakheart is the youngest ever master of the Oakheart Style, possibly the most deadly martial art in the Imperial Trust. Martial Art designed for humans anyway.
An Interesting Education (+4L, +4C, +2 to all other stats)- Jacob Oakheart has had an interesting education, ranging from the normal for a member of the Avernite upper class to the strange, excessive and often crazy teachings of his mother and her colleagues. This has given him a wide range of skills and knowledge, including some that it is impossible for him to use.
Push Past your Limits (+1P, +2C, more liekly to gain traits)- Jacob Oakheart believes that you should always strive to push beyond your current limits in order to improve, and he trains in a manner that demonstrates this.
Avernite Survivor (+2C)- By surviving several decades of life on Avernus Jacob has proven himself to be a skilled warrior.
Team Leader (+3M when commanding platoon size units or smaller, +15 unit morale when commanding platoon sized units or smaller)- In his time in the Psyker Hunters Jacob Oakheart has become highly skilled at leading small groups in the face of seemingly impossible odd, though his leadership style does not scale up well.
Jacob Oakheart is the adopted son of Arbitrator Jane Oakheart and is in effect your only nephew. He first came to his mothers attention at the age of five when he killed an Ammut Crocodile with a dagger, a feat that would be considered impressive for a fully trained adult. After being adopted he proved to be exactly the right type of son for Jane, able to not only keep up with the near torture she considers training but to enjoy it.
Jacob had an interesting childhood, as his mother alternated between having him attend some of the best schools on Avernus and either teaching him herself or having some of her friends and colleagues instruct him. This has somehow resulted in both a well adjusted young man and one with an wide range of skills and knowledge. You are still not sure why Ridcully had him learn the theoretical basics of each of the psychic disciplines however, he has no psychic talent to speak of.
After graduating Jacob attended the Psyker Hunter Academy, where he set records in a range of topics and graduated at the top of his class. He then joined the Psyker Hunters at the age of twenty-two, one of the youngest on records. Jacob quickly distinguished himself and became both the youngest Veteran Psyker Hunter on record and the youngest Psyker Hunter Sergeant on record. However he first rose above the pack at the age of thirty three when he singlehandedly killed Rob Vörös, a Beta-level Diviner/Telepath that his squad stumbled across. While this victory was mostly a result of luck it still demonstrated the sheer level of skill in combat that he has, and earned him a promotion to the rank of Elite Pysker Hunter, at under half the normal age.
In person Jacob is a friendly well adjusted young man, though he raises several alarm bells for the average Avernite. This is mostly because he is to calm and confident, and lacks the nervous twitch that almsot every Avernite that reaches adulthood develops. This has actually led to him being considered a offworlder by many, at least until they see his unconsciously killing spiders. Instead many consider him an elder, as usually only the oldest and most skilled Avernites develop the natural combat readiness that he displays.
