Melena Omi was a female Satedan who worked in a hospital on Sateda. She was engaged to Ronon Dex. In 1998, during the Wraith attack on Sateda, Ronon tried to convince her to leave Sateda. However, she refused, saying the Hospital was going to need her. Ronon had to stay and fight, while she stayed in the hospital. After all of Ronon's soldiers were killed, he went to the hospital to try and convince her to leave again, but she again refused. Mere seconds later, Melena was killed in an explosion. Upon being made a Runner again, Ronon was returned to Sateda and had flashbacks of the fall of the planet, including Melena's death. He took cover in the same spot she died in as 25 Wraith came after him all at once. Melena's death and that of the rest of Sateda was avenged when Doctor Carson Beckett killed the Wraith Leader responsible for the attack with a Puddle Jumper's drone weapons. (SGA: "Sateda")
Ronon mentioned at one point to Doctor Jennifer Keller that he was never married, but "close enough." Ronon confirms to Radek Zelenka that he had been betrothed to a Satedan and it was Melena. (SGA: "Quarantine", "Legacy: Homecoming")
