Firstborn
When Alexander shows little interest in warrior training, Worf takes him to a Klingon outpost’s Kot’baval festival, celebrating the battle between Kahless and the tyrant Molor. They are almost killed by an assassin apparently from the Duras family. A strange man named K’mtar shows up, who claims to be a friend of the family. When the Duras sisters are confronted with the knife that was used to attack Worf and Alexander they find the seal of B’etor’s son, but B’etor only just learned herself that she was pregnant. It turns out that K’mtar is Alexander from the future who is going to avoid to become a pacifist diplomat who couldn’t help his father when he was assassinated in the Klingon High Council. summary by Ex Astris Scientia
