You're getting what I say but! "Assassins Battle" was not a battle, it never happened. I want you to look on the Wiki and forums for appropriate lore pieces
Tom is a assassin that was kidnapped as a kid and escaped. He found himself in the middle of no where and found a cart with someone in it sleeping. He then got a rock and repeatedly smashing the sleeping mans head until he died. He then got into a town and stole money to survive. After that he trained for hours and hours until he was good. He was then meet by a few people and hired as a trained professional assassin. He then goes on with his day by sneaking into peoples houses or sneaking to spy on someone and stealing money. If he is payed to kill someone he will do it the most quietly and damaging way possible. His use of weapon is mostly a small blade which is extremely sharp. Tom also joined a town in the name as in Markev which is a northerner town, in the Kingdom of Haense.
