Wow, thank you so much for playing and for your feedback! I'm so glad to hear you're enjoying it!
Regarding the puzzle you're stuck on, a few questions/clues:
1. Have you revealed all the crayon colors in the box? (Not the missing crayons, just the white ones that were already there when you found the box).
2. Have you asked "Erevyn" about Castelyn? Did she give a description of what she was wearing the last time she saw her?
3. How does that compare to the warrior drawing in Maya's sketch book?
Hopefully that's enough of a nudge to move you forward. If you're still stuck, let me know!
