Wouldn’t doubt it. While she is dead, the story is told in past tense, so this could either be a past Dawning, or an ornament for a friend passed away. It does specifically state in the Recluse tab that it’s a “friendship”, so I really do think it’s Mara, but you never know.

It’s possible that it was for Sjur and Shaxx didn’t know she was dead until he tried giving it to her. We don’t know if Shaxx liked Mara or Sjur. We’ll need to wait for more information.
