Alsia was a female humanoid of an unnamed species who visited Deep Space 9 in mid-2370, where she met an El-Aurian con artist named Martus Mazur. Recently widowed, Alsia had managed to put away a bit of latinum every year, just for herself, when she and her husband had run their business together. After he died, she had quite a little sum, but not enough for the future. So to live out her retirement, she decided to invest it all and purchasing the mining concession for the entire Vlugta asteroid belt.
