Percy Jackson and the Olympians: Legends

T.J. has dark skin, short curly hair, a lanky build, and is always described to be wearing his blue woolen coat from the American Civil War, with brass buttons and chevrons, and it is revealed that he was a infantryman.

T.J. was the first of Floor 19 to greet Magnus properly upon his arrival, quickly earning Magnus' approval. He is overtly friendly and quick to put his trust in people. T.J. is quite talkative, Mallory claiming he "will take forever answering a yes/no question." He shows a resistance to breaking the rules, (possibly stemming from his father being the Norse god of law,) but ultimately his loyalty outweighs it. He is also shown to be brave and a natural leader, taking the head of Floor 19's charge in battle training. T.J.is also very optimistic and has to accept any personal challenge with saying "I ACCEPT".

Thomas Jefferson Jr. (mostly known as T.J.) is a Norse demigod son of Tyr and a woman who escaped slavery. A veteran of the American Civil War, Jefferson became one of Odin's einherjar. He was born in Massachusetts, and was killed during the assault on Fort Wagner, South Carolina. After dying in battle he became an einherji. T.J. invited Magnus Chase to breakfast with the rest of the residence of their hall. He explains how the nine worlds work and that a person can leave the hotel anytime with or without permission but discourages it because the results could be dire. The horn then sounds for training and the hall mates head out. During the battle practice, he tries to take a hill but is killed. He charges the Valkyries, and the others cover Magnus's escape to Midgard.
