Aladra Thau was an Ubessian female child.
During the Federation-Cardassian War, Starfleet and Cardassian forces clashed over the planet, sending a Starfleet starship crashing to Ubessi's surface, causing a massive matter-antimatter explosion, destroying most of the main city and polluting the planet. Aladra, her mother, and her brother died, while Yaghim and his colleagues, protected in a military command bunker near an engineering assignment they were undertaking, survived.
