|Relatives|| Vellamo (Daughter)
The femme-fatale Sedna is of a mysterious and seductive woman whose charms ensnare her lovers--in this case, Neptune--often leading them into compromising, dangerous, and deadly situations.
When Neptune's ship was raided by Sedna and her brothers, they were having a sword fight when Sedna cut his across his nose which is why he has a scar there. Sedna had won the dual. Since she is a very skilled swordsmen. She hardly ever loses a dual, and that day was no different. She defeated Neptune, took him captive, got to know him a little, and released him a few days later.
Though it may seem Sedna doesn't have a last name, she does. But since her family dropped the surname generations ago, no one can really remember what it actually is.
