I'm thinking maybe a Leeka/Brisa thread? I what Leeka to start finding her niche and Brisa is the Glazier of the Edge. Leeka almost took an interest in crafting but well... it drifted away. Maybe she could shadow Brisa while she's working?
Leeka and Aeolus could thread too, something playful perhaps.
Hearth can maybe crash with Telesaan and Rhea sometime. She's just chilling everywhere.
