[@PerseusArchean] It's all a bit of a mess when you think about it, because Jera would have access to her father and mothers knowledge of magic and be able to possibly counteract a curse or even try to curse Ox in retaliation! It would be like a Cold War/Mutually assured destruction thing.
And then considering Ox is a skilled necromancer, Jera would probably take issue with Ox killing his mother, since his necromancy means he could probably bring her back from death/the underworld but simply chooses not to. I could see some barbs being exchanged wirth both being forced to endure the other merely because neither has a sure fire way of taking out the other while ensuring their own safety.

And if anyone took out Odin, Jera would likely be [i]pissed[/i] since she pretty much feels there are few even worthy enough to challenge him. If they actually killed him, Jera would consider it an insult to her bloodline. I picture Jera getting along with the Norse pantheon. When you think about it, the only child of Odin that really plotted against him was Loki. Thor, Baldr, Vidar and Váli had no problems with him, so I don't see Jera taking much of a disliking to him, or even Odin seeing her as a threat.
