Wren's Memories
Wren shares her memory from Sage in Episode 102: The Always Storm.

A memory from before the attic.

''I'm sick. I'm in bed and sweating and half-delirious with fever. I can't get comfortable and I keep sneezing and coughing and my throat hurts. I'm thinking about getting up and making tea or something, but I just don't have the energy. So I lay in bed and feel miserable and try and fail to sleep. At some point, I notice a pain in my chest different from the other flu symptoms I'm having. It's a sharp jagged pain, climbing slowly up my chest, getting closer to my throat every time I cough. Finally, I spit something up. It's hard and angular and it nearly cracks my tooth.''

''Shaking, I turn on the light on the bedside table. There in my hand is a deep green gem. An emerald. Then I wipe my forehead where I've been sweating with fever, and my fingertips shimmer with tiny particles of diamond.''
