Heleen was a native of her home world, Lucius' planet.
She became one of Lucius Lavin's six wives before the Atlantis expedition became aware of Lucius' activities. After they learned the reason why people started to love him and get sick, due to Lucius' herb, Dr. Carson Beckett engineered a serum that neutralizes the effect of the herb. After she learned the truth, she divorced him. (SGA: "Irresistible")
