She and Roo are friends! In my au- Roo is very fond over Lyra. Lyra is just below The Morningstars in terms of power. Not only does she get her power from Rosie, she also gets her power from Roo! She made a deal with Roo, Lyra is an access point for Roo and in return, Roo supplies Lyra power. Roo is confined to Lyra though, it's similar to Alastor and his shadow. Roo is allowed to sulk in the shadows, which is actually why in my au, Lyra has no shadow because Roo is her shadow. Her soul is not owned, she was able to slip her way out of that part with Rosie. (my au is a bit different from canon) Everyone owns their own souls in my au. Power is gained by the number of contracts you have.
