Nia was the Queen of Azgeda who attempted to overthrow Lexa

Nia was born to King Theo and an unknown mother. At one point in her life she took over the throne of Azgeda and became the Queen. Sometime in her adulthood she gave birth to a son and named him Roan

Nia also kidnapped the lover of Lexa, Costia, whom she used for information about Lexa, then killed Costia. Commander Lexa then ordered the only way Azgeda could join the Coalition was if she banished her son Roan, so she did so
