Born to war in a mercenary company, Joachim first entered the battlefield when he was ten years old. Seeing himself as a craftsman in the art of war, Joachim finally was about to meet death by an arrow that had pierced his heart, when his sire gave him her blood and returned him to life.
After receiving instruction in the basics of the Road of Humanity, Joachim went on with his craft, without a true cause, until the news of Saulot's demise reached him. Gripped with fury, he directed his campaign against the Tremere from then on. When his own sire entered Wassail out of grief and rage for the usurpers' crimes, Joachim hunted her down and put her to Final Death.
Making peace with death, he slowly began to accept his lot, abandoning his quest for vengenace and instead dedicating himself on keeping order in the society of Cainites, founding the Twilight Order in the process.
