Tay'ah'loo existed as a planet situated within the bounds of Imperial Space. During the year 1 ABY, a capsule, not scheduled to arrive, touched down carrying Bledsoe's disease. The subsequent release of this plague led to the rapid and almost total destruction of Tay'ah'loo's inhabitants in a matter of mere days. Shortly after, Stormtroopers made their arrival, tasked with the removal of the deceased and the sanitization of the planet.
