Hela was Odin's daughter. In the past, Odin was a more war - like figure, and Hela was his enforcer. She helped him conquer many lands. However, as Odin's views changed, he saw Hela as a threat to the peace he now desired. So, he banished her. Odin didn't want her to continue her reign of terror. This is the basic hela and odin back story which led to a lot of conflict when Hela finally broke free from her prison in the later storylines.
The key elements include Hela's origin as Odin's firstborn. Her role as a powerful weapon in Odin's early conquests. And then Odin's transformation which made him see Hela as a danger. He feared that she would continue her violent ways and disrupt the peace he was trying to build. So, he took the step of locking her away, which is a major part of their back story.
Another possibility is Heimdall. As the all - seeing guardian of the Bifrost, he would be aware of Odin's situation from the start. He could be the one trying to piece together what happened to Odin and prevent any disasters that might occur as a result of Odin's wipe. His unique abilities and loyalty to Asgard would make him a strong candidate for the main character.
